Abstract
Combined homicide-suicides have been classified based on the psychopathology of the perpetrator and the nature of the relationship between perpetrator and victim(s). To further understand the nature of this tragic phenomenon and to test the validity and practicality of a previously suggested classification system, investigators systematically collected data on all combined homicide-suicide events that occurred in Galveston County, Texas over a continuous 18-year period (n = 20). The most common psychopathological finding for perpetrators was high serum alcohol levels that suggested intoxication. Most combined homicide-suicides fell into one of the relational categories and most of these, as predicted, were of the consortial type, possessive subtype. As expected, due to the small sample size, the less common types of combined homicide-suicide were not represented in this sample.

Abstract
The stroke classification developed for use in the Oxfordshire Community Stroke Project (OCSP) is simple, clinically meaningful and requires no investigations. However, its inter-rater reliability in a community setting is unknown. We aimed to assess the inter-rater reliability of this classification among neurologists and nurses within a community-based stroke incidence study. Fifty-four stroke patients with cerebral infarction who were registered in the North East Melbourne Stroke Incidence Study (NEMESIS) were assigned OCSP classifications by two neurologists and one of seven research nurses. There was moderate agreement between neurologists (kappa = 0.53), fair agreement between neurologist 1 and nurse (kappa = 0.31) and moderate agreement between neurologist 2 and nurse (kappa = 0.45). Disagreement about the neurological signs was an important reason for classification differences. The OCSP classification can be easily applied in a community setting with moderate inter-rater reliability and is thus a useful instrument for commun ity-based epidemiological studies.

Abstract
The purpose of this study was to determine changes in regional cerebral blood flow (rCBF) associated with premenstrual syndrome (PMS). Regional CBF was examined using single photon emission computed tomography (SPECT) in seven women who sought treatment for PMS and seven control subjects. Confirmation of PMS was based on the Daily Symptom Report (DSR) of 17 common symptoms associated with PMS. A first SPECT scan was performed near the peak of premenstrual symptoms based on DSR reports from the two previous cycles. A second scan was performed in the postmenstrual period. Prior to scanning, each subject had a Hamilton Depression Rating Scale (Ham-D) obtained. Regions of interest were drawn on the images to generate mean counts per pixel, and normalized to the cerebellum. Activity in the frontal, temporal and parieto-occipital cortices, and the thalami and basal ganglia, were compared between the two scans. Correlations between activity in each region of interest and Ham-D values were also determined. There were marked decreases in rCBF in the temporal lobes on the premenstrual scan compared to the postmenstrual scan in PMS patients. Significant correlations were observed between the change in rCBF in the right and left temporal lobes and the changes in Ham-D scores (r = 0.91, p < 0.01 and r = 0.86, p = 0.01 respectively). No rCBF changes were observed in controls. We conclude that SPECT imaging demonstrates modest decreases in rCBF in the temporal lobes that correlate with the level of depression in subjects with PMS.

Abstract
CONTEXT Women in Great Britain may obtain abortions only if they meet certain criteria and the procedure is approved by two physicians. Since seeing a general practitioner is typically a woman's first step toward obtaining an abortion, these doctors' attitudes about the procedure are very important. METHODS In 1999, a random sample of 702 general practitioners participated in a mailed survey regarding their attitudes toward abortion and the British Abortion Act. RESULTS Four in five respondents considered themselves broadly prochoice, and three in five believed that the current law should be liberalized to give women the right to obtain an abortion without regard as to reason. Three-quarters of doctors favored government provision of free abortions, and one-quarter thought that the current law places an unreasonable burden on general practitioners. However, physicians' opinions about whether the abortion decision should be the woman's alone depended on the pregnancy's gestation, and three-fifths of respondents said that the law was appropriate. Among doctors who were broadly antiabortion, one-fifth favored women's right to choose, and two-thirds supported the current law; however, nearly half opposed government funding of abortion services, and one-quarter did not feel that physicians need to reveal their antiabortion stance to patients. CONCLUSIONS Although Great Britain's abortion law is more restrictive than those in many other developed countries, general practitioners have largely positive attitudes toward women's access to abortion and toward the existing law. Their occasionally contradictory views, however, suggest that some areas are potentially problematic.

Abstract
Dehydroepiandrosterone (DHEA), an androgenic steroid hormone, exhibits an age-related decline. Perimenopausal women have only approximately 50% of peak DHEA levels. Despite limited scientific data, DHEA has gained recognition as a dietary supplement to reduce the symptoms of aging and improve well-being. This randomized, double-blind placebo-controlled trial examined the effects of 50 mg/day of oral DHEA supplementation, for 3 months, on 60 perimenopausal women with complaints of altered mood and well-being. Changes in the serum endocrine profile of women in the DHEA group were significantly greater than the placebo group, including a 242% [95% confidence interval (CI) +60.1, +423.9] increase in DHEAS, a 94.8% (95% CI +34.2, +155.4) increase in testosterone, and a 13.2% (95% CI -27.88, +0.5) decline in cortisol compared to baseline. Women receiving DHEA had a 10.1% (95% CI -15.0, -5.1) decline in high-density lipoprotein and an 18.1% (95% CI -32.2, -3.9) decline in Lp(a) from baseline, but these declines did not significantly differ from women who received placebo. Women receiving DHEA did not have any improvements significantly greater than placebo in the severity of perimenopausal symptoms, mood, dysphoria, libido, cognition, memory, or well-being. DHEA supplementation significantly effects the endocrine profile, may affect the lipid profile, but does not improve perimenopausal symptoms or well-being compared to placebo.

Abstract
Approximately half of the 40-50% of North American women who crave chocolate or sweets do so principally in the perimenstrum, the part of the menstrual cycle surrounding the onset of menstruation. We test two hypotheses about the events that trigger these cravings: 1) the premenstrual drop in progesterone levels; or 2) dysphoria or tension in the perimenstruum. Chocolate craving, sweets craving, and other perimenstrual symptoms were rated daily for six menstrual cycles by a sample of women with severe premenstrual syndrome (PMS). Forty-four women satisfied criteria for cyclicity in chocolate craving, and 44 for sweet craving, determined during the first two cycles. Thirty-four subjects satisfied criteria for craving of both chocolate and sweets. After placebo treatments during the third cycle, subjects were randomly assigned, double blind, to administration of placebo, oral micronized progesterone, or alprazolam (a tranquillizer). Treatments were administered from the beginning of the third week to the second day postonset of menstruation during the fourth to sixth months of study. Neither progesterone nor alprazolam decreased chocolate or sweets craving.

Abstract
Does the evidence now available support the concept of premenstrual dysphoric disorder (PMDD) as a distinct clinical disorder such that the relative safety and efficacy of potential treatment can be evaluated? In a roundtable discussion of this question, a wealth of information was reviewed by a panel of experts. The key characteristics of PMDD, with clear onset and offset of symptoms closely linked to the menstrual cycle and the prominence of symptoms of anger, irritability, and internal tension, were contrasted with those of known mood and anxiety disorders. PMDD displays a distinct clinical picture that, in the absence of treatment, is remarkably stable from cycle to cycle and over time. Effective treatment of PMDD can be accomplished with serotinergic agents. At least 60% of patients respond to selective serotonin reuptake inhibitors (SSRIs). In comparison with other disorders, PMDD symptoms respond to low doses of SSRIs and to intermittent dosing. Normal functioning of the hypothalamic-pituitary-adrenal (HPA) axis, biologic characteristics generally related to the serotonin system, and a genetic component unrelated to major depression are further features of PMDD that separate it from other affective (mood) disorders. Based on this evidence, the consensus of the group was that PMDD is a distinct clinical entity. Potential treatments for this disorder can now be evaluated on this basis to meet the clear need for effective therapy.

Abstract
Amplification of an 800-base template was verified in a 10-min test on a 2-microL sample of the PCR product solution. For verification, digoxigeninylated primers and biotinylated d-UTP-16-biotin were added to the amplification solution. The resulting amplified product was digoxigeninlabeled at its 3'-end and was also labeled with multiple biotin functions along its chain. The detecting electrode was coated with an electron-conducting redox hydrogel to which anti-digoxin monoclonal antibody was covalently bound. The amplified DNA was captured by the electrode through conjugation of its 3'-digoxigenin with the antibody. Exposure to a solution of horseradish peroxidase-labeled avidin led to capture of the enzyme and switched the redox hydrogel from a noncatalyst to catalyst for H2O2 electroreduction. The switching resulted in an H2O2 electroreduction current density of 2.1 +/- 0.9 microA cm-2 in 10-4 M H2O2 at Ag/AgCl potential and at 25 degrees C.

Abstract
CONTEXT Premenstrual dysphoric disorder is an important cause of symptoms and functional impairment in menstruating women. OBJECTIVE To evaluate the efficacy of sertraline hydrochloride for treatment of premenstrual dysphoria by measuring changes in symptom expression and functional impairment. DESIGN Two screening cycles followed by 1 single-blind placebo cycle and 3 cycles of randomized, double-blind, placebo treatment. SETTING Twelve university-affiliated outpatient psychiatry and gynecology clinics. PATIENTS Of the 447 women who requested participation, 243 met criteria for premenstrual dysphoric disorder and were randomized; 200 women completed the study. INTERVENTION A flexible (50-150 mg) daily dose of sertraline hydrochloride. MAIN OUTCOME MEASURES The Daily Record of Severity of Problems, Hamilton Rating Scale for Depression, Clinical Global Impression Scale, and Social Adjustment Scale. RESULTS Mean (+/-SD) total daily symptom scores decreased significantly (P<.001) in the sertraline-treated (64+/-22 to 44+/-19) compared with the placebo-treated (62+/-22 to 54+/-24) groups. Significant improvement (P<.05) was found for all clinically derived symptom clusters (depressive, physical, and anger/irritability symptoms). Hamilton Rating Scale for Depression scores decreased by 44% and 29% in the sertraline and placebo groups, respectively (P<.002). End-point global ratings showed much or very much improvement in 62% of the active treatment group and 34% of the placebo treatment group (P<.001). Reported functional impairment was substantial at baseline. Improvement in psychosocial functioning with treatment was similar to what is found in studies of major depression. CONCLUSIONS Sertraline was significantly better than placebo for treatment of premenstrual dysphoria as reflected by symptomatic improvement and change in reported functional impairment. Serotonin reuptake inhibitors such as sertraline are useful therapeutic options for women with premenstrual dysphoria.

Abstract
Orthodontic and surgical treatment of patients with maxillary retrusion and/or midface hypoplasia is challenging. This study was designed to show that the maxilla can be successfully lengthened by surgical assisted rapid orthopedic movement, using the principles of distraction osteogenesis. Three experimental and three control adolescent cynomolgus primates were used in this study. Metallic markers were placed in the cranial base and the maxilla and cephalometric x-ray films were taken. An orthodontic appliance was constructed with a Glen-Ross screw (Dentaurum, Newtown, Pa.) oriented anteroposteriorly. Anterior supraapical osteotomies of the maxilla were carried out. Bilateral horizontal and interdental osteotomies were created between the first premolars and the canine; the anterior six tooth dental-osseo segment was completely mobilized in all animals. Beginning 1 week after surgery, the orthodontic appliance was opened a quarter turn every 2 days until the anterior segment was advanced by 4 mm in two animals and 6 mm in one animal. Animals were killed at 6, 8, and 12 weeks after completion of the maxillary orthopedic advancement. Computerized tomographic scans of the maxillae were completed, and the specimens were then prepared by routine histologic methods for examination by light microscopy. The computerized tomographic scans showed bone deposition in the osteotomy sites, which was confirmed by histologic observations. Since this technique demonstrated repair by bone rather than soft connective tissue in the osteotomy sites, this procedure could be a useful method of treating midface retrusion.

Abstract
PURPOSE To explore the potential for the information superhighway to provide radiologists with new opportunities. MATERIALS AND METHODS The Internet was used as the communication and distribution medium. MOSAIC, a graphical interface, provided access for clients, and a computer was used to serve text, images, sound, and cine onto the Internet. RESULTS The system can be used to send reports and images to referring physicians or consulting radiologists; to provide a large database that is constantly available; to provide an increasing collection of teaching files; and to distribute interactive, multimedia teaching tools that can be used on any computer system. The use of the MOSAIC interface facilitates interaction, which allows users with limited computer experience to access the system. CONCLUSION The Internet can dramatically expand the ways radiologists interact with their colleagues. These preliminary results indicate that there will be great challenges and opportunities for improving care and teaching in the future.

Abstract
A recent study has shown that the maxilla in primates can be successfully lengthened (0.5 mm every other day up to 6.0 mm) by means of surgically assisted-rapid orthopedic movement, using the principles of distraction osteogenesis. The present study was designed to determine if the maxilla can be advanced at a faster rate and if relapse would occur after removal of the orthodontic appliance. Metallic markers were placed in the cranial base and maxilla of two Cynomolgus primates, and cephalometric radiographs were taken. Bilateral horizontal and interdental osteotomies were created between in the first premolars and the canines, and the anterior segment was completely mobilized. An orthodontic appliance was bonded to the teeth and the screw was closed, compressing the osteotomy site. One week postoperatively the appliance was opened four quarter turns every day until the anterior segment was advanced by 10 mm. Cephalometric radiographs were taken at 6, 8, and 12 weeks postadvancement. At 12 weeks, the orthodontic appliance was removed, and at that time and 2, 4, and 6 weeks later, cephalometric radiographs were taken and study models fabricated. At the end of the postretention period, the animals were sacrificed, and the maxillae were evaluated by light microscopy. Results showed that the maxilla can be successfully advanced at a faster rate and for longer distances, and that the advanced maxilla does not relapse during the 6-week postretention period.

Abstract
This study proposes the development of an intraoral surgical approach to distraction osteogenesis to treat maxillofacial defects. Bilateral sagittal split osteotomies were made in the ascending ramus and body of the mandible of two adult cynomologus primates, and the dento-osseous segment was completely mobilized. A distraction device was fabricated from a Glen-Ross screw soldered between two mini bone plates. The bone plates were fixed by self-tapping screws to both right and left proximal and distal mandibular segments. Beginning 1 week postoperatively, both distraction plates were opened 1 mm every day until the mandible was advanced a total of 10 mm. Comparison of cephalometric radiographs and study casts prepared preoperatively, at the completion of the mandibular orthopedic advancement, and up to 12 weeks postdistraction, showed that mandibular advancement was successful and stable. There was radiographic evidence of bone filling the osteotomy sites, and there was no scar tissue formation or evidence of relapse.

Abstract
Seeking ways to improve their health, gay men with human immunodeficiency virus (HIV) infections living in San Francisco are developing information networks and patterns of self-care behavior. Drawing from a set of explanatory theories, this cross-sectional survey with retrospective elements examined patterns and potential predictors of information-seeking activity in a cohort or 162 HIV seropositive (HIV+) men, 60 of whom provided complete data sets. The study suggests that 1 year after becoming aware of an HIV+ health status, most patients have developed multifaceted information networks. The amount of tangible aid acquired from these networks and frequency of consultation is positively related to patterns of HIV self-care behaviors and "feeling calm" (p less than 0.01), suggesting that these variables may be important markers for the need of supportive-educative nursing care. Suggestions for nursing practice and research are also described.

Abstract
The purpose of this study was to conduct a direct comparison of two dose regimens of minocycline to determine 1) whether they achieved crevicular fluid concentrations in a therapeutic range; and 2) the frequency of side effects. In a double-blind design, 30 patients divided into 2 groups were given either 100 mg minocycline or 200 mg minocycline per day for an 8-day period. The concentration of minocycline in the gingival clevicular fluid (GCF) at 8 days was 4.77 micrograms/ml for the 100 mg a day group and 5.97 micrograms/ml for the 200 mg a day group and at 15 days was 4.30 micrograms/ml for the 100 mg a day group and 4.17 micrograms/ml for the 200 mg a day group. There was no significant difference in the antibiotic concentration in the gingival crevicular fluid between the 2 groups. Reported adverse experiences to the minocycline were greater in the 200 mg a day group. Short-term changes in periodontal health as measured by plaque index, gingival index, pocket depth, and bleeding upon probing showed improvements in all parameters over the 15 day period. There were no significant differences in these parameters between the 100 mg a day and 200 mg a day group. At 8 days reduced levels of Porphyromonas gingivalis and Prevotella intermedia were achieved but they were not eliminated from infected subgingival sites in either group. Achieving bacteriostatic concentrations of GCF, fewer side effects, and the potential for better compliance suggests that a single daily dose of 100 mg minocycline should now be investigated for its efficacy in managing periodontal infections manifesting as periodontitis.

Abstract
Although treatment of HIV infections is possible, anecdotal data and research suggest that infected homosexual and bisexual men are developing sets of HIV-specific self-care behaviors that they believe will maintain their health or delay progressive disease. However, little is known about frequent use of HIV self-care in relationship to symptom distress or other factors commonly assessed by nurses. These deficits limit the ability of healthcare providers to intervene appropriately. Consequently, the following repeated-measures study retrospectively examined correlates of HIV self-care in 162 outpatients who were attending a major healthcare facility in San Francisco, CA. Standard and HIV-specific instruments created for the study were used in data collection. Results suggest that the men increased their use of 35 of 81 HIV self-care behaviors once they became aware of being HIV seropositive (p less than 0.001). Frequent use of HIV self-care behaviors was related to several variables, including previous patterns of self-care (p less than 0.001), and AIDS diagnosis (p less than 0.01), and a locus of control (LOC) indicator (e.g., the statement "What happens to me is beyond my control") (p less than 0.001). Symptom distress also was related to several variables, including selected LOC and quality-of-life (QOL) indicators, mood states, and recent diagnosis of selected AIDS-related diseases (p less than 0.01). Collectively, these results suggest that taking self-care and selected psychosocial histories will allow nurses to identify ambulatory patients with HIV infections who need intensive care.

PATIENTS Six critically ill patients (51-78 years) who required ventilation and parenteral nutrition and six age, weight, height, and sex-matched healthy adults were studied. MEASUREMENTS The patients and controls were studied for two 24-hour periods; the patients before and after starting parenteral feeding, and the controls during a 36-hour fast and when taking meals equivalent in calories and protein to the patients' parenteral feed. Serum GH was measured at 20-minute intervals and analysed by a pulse detection algorithm (Pulsar) and Fourier transformation. IGF-I was measured at 0, 12, and 24 hours. RESULTS Patients had low serum IGF-I levels compared with controls, whether fasted or fed, despite having mean GH levels similar to fasted controls. For fasted patients vs fasted controls the mean (+/- 1 SD) GH levels were 4.5 +/- 2.0 vs 4.0 +/- 2.4 mU/l respectively, and IGF-I levels at the end of the fast were 0.17 +/- 0.11 vs 0.78 +/- 0.29 U/ml (P = 0.003). Patients showed elevated baseline GH levels compared with controls when fasted and during parenteral feeding (patients vs controls fasted 3.1 +/- 1.9 vs 0.8 +/- 0.5 mU/l, P = 0.01; patients vs controls fed 4.2 +/- 4.5 vs 0.5 +/- 0.04 mU/l, P = 0.028). Fourier transformation confirmed oscillatory GH levels in the controls, fasted or fed, but this activity was attenuated in the patients. Parenteral feeding had no effect on the GH profiles or IGF-I levels of patients, but controls showed greater mean GH levels during their fast than when fed. CONCLUSIONS We have demonstrated that critically ill patients have low IGF-I levels associated with augmented baseline GH levels which show reduced oscillatory activity. The results would be compatible with the hypothesis that there is an adaptive change in critically ill patients away from the indirect effects of GH (stimulation of IGF-I production and anabolism) and toward the direct effects (lipolysis and insulin antagonism) which increase the availability of energy substrates. The pattern of GH levels seen in our patients may be important in this adaptation.

Abstract
Abstract Pyridostigmine, an acetylcholinesterase inhibitor, stimulates growth hormone (GH) release and is thought to act by inhibiting hypothalamic somatostatin release. There are few data concerning the effect of pyridostigmine on other pituitary hormones apart from GH. We have studied the effect of pyridostigmine on basal GH, thyrotrophin (TSH), prolactin, adrenocorticotrophin and cortisol release, and thyrotrophin-releasing hormone (TRH)-stimulated TSH and prolactin release, in two studies involving nine healthy male subjects. Pyridostigmine stimulated GH release in all subjects but had no effect on adrenocortocotrophin or cortisol levels, or basal or TRH-stimulated TSH and prolactin levels. There are some data to suggest that somatostatin inhibits TRH-stimulated TSH release. Our findings, however, suggest that either endogenous somatostatin tone has little effect on the TSH response to TRH compared to its effects on GH or pyridostigmine acts through a mechanism other than altering somatostatin tone. Pyridostigmine did not alter adrenocorticotrophin or cortisol levels in the presence of a clear action on GH release, providing further evidence that the previously reported effects of cholinergic drugs on cortisol release are stress-related.

Abstract
Progesterone is the most widely used treatment for premenstrual syndrome. To answer definitely the question of whether progesterone suppositories are effective for the treatment of premenstrual syndrome, a randomized, placebo-controlled, double-blind crossover study of 168 women, receiving progesterone in doses of 400 and 800 mg or placebo, was carried out. Premenstrual symptoms were not significantly improved by progesterone compared with placebo in any measure used in the study, including daily symptom reports maintained throughout treatment, clinician evaluation of improvement, and patient global reports of symptoms severity, relief, and disruption of daily activity. No symptom cluster or individual symptom differed significantly between progesterone and placebo treatment. These treatment results were not significantly affected by fluctuations in response during the placebo washout period, pretreatment levels of depression or anxiety at either postmenstrual or premenstrual times, or any of 19 other background, medical history, or symptom variables examined individually as covariates with treatment.

Abstract
The Neurobehavioral Rating Scale (NRS) has been used in the rapid bedside assessment of closed head-injured and stroke patients in the past and has been found to be highly predictive of long-term outlook. The NRS consists of 27 items in a Likert-type scale and measures cognition and behavioral parameters of brain disease. The NRS was administered to nine human immunodeficiency virus (HIV) positive individuals in a pilot interrater reliability study. Highly significant correlations (r .94 and r .97; p less than .001) were found between interviewers. Content and construct validity had already been established in prior research. To date, no quick, easy assessment tool measuring both cognitive and behavioral manifestations in this population has been widely used. Therefore, it becomes imperative that such a tool be available to nursing staff to aid in monitoring of neurologic deterioration, assist in appropriate placement of acquired immunodeficiency syndrome (AIDS) dementia complex patients and planning of care.

Abstract
To characterize the symptoms associated with premenstrual syndrome (PMS), the menstrual symptom calendars of 100 women diagnosed with PMS were factor-analyzed. Scores on 18 symptoms were recorded daily for one menstrual cycle prior to the women's first clinic visits. Two factors were found to predominate throughout the cycle: The first included emotional and behavioral symptoms and the second included physical and cognitive symptoms. The two factors were constant throughout all the phases of the menstrual cycle. Emotional symptoms clustered together throughout the menstrual cycle and were the dominant symptoms on factor I. However, they loaded (correlation of the variable with the factor) on factors I and II during the postmenstrual phase. Behavioral symptoms loaded on factor I throughout the menstrual cycle; however, they were prevalent predominantly in the later half of the intermenstrual and the premenstrual phases. Physical symptoms loaded predominantly on factor II and were less prevalent than the emotional symptoms. The cognitive symptoms loaded on factor II during the premenstrual phase. These findings are relevant for defining PMS criteria for women who seek treatment.

Abstract
A large number of direct bonding systems have been introduced for use by dentists and dental hygienists. Although these agents are used for direct bonding of brackets to enamel, contact with skin, oral mucosa, and gingiva is not uncommon. These products have wide clinical use, but their biocompatibility characteristics have not been extensively investigated. The present study was undertaken to determine the effects of the primer component of Mono-Lok (Rocky Mountain) and the primer component of Control (Lancer Pacific) on skin. Three adult Macaca mulatta monkeys were used in the study. The skin on their backs was shaved and the primer component of Control, primer component of Mono-Lok, and saline solution were applied at different sites every 3 days for up to four applications. The skin was examined clinically and, 5 days after the last application, a biopsy was performed for histologic evaluation. The skin in contact with the primer component of Mono-Lok exhibited pronounced inflammatory changes and was characterized by swelling, vesiculation, and ulceration. Histologic observations confirmed these findings by showing a marked inflammatory cellular response characterized by eosinophils. In contrast to these findings, the skin in contact with the primer component of Control or saline solution exhibited normal architecture. Histologic observations supported this appearance and showed minimal inflammatory cell infiltration. These results show that there are differences in the biocompatibility of direct bonding systems and that further studies are needed to clarify their long-term effects on patients and dental personnel.

Abstract
The precise factors mediating both initial cell attachment and longer term connective tissue reattachment after tissue destruction due to periodontal disease are not known. An in vitro model was used to assess initial attachment of fibroblast-like cells to periodontally-diseased root surfaces. Root fragments were obtained from freshly extracted teeth from 6 different patients. Individual roots were prepared such that a comparison could be made of initial attachment to non-instrumented diseased root surface, curetted diseased root surface and the non-diseased, non-instrumented portion of the same root. The amount of hard tissue removed by instrumentation was quantitated and kept constant between 0.9-1.0 mm. The unsterilized fragments were incubated with human gingival fibroblasts (HGF) for 1 h at 37 degrees, after which the roots were first washed to remove non-adherent cells and then photographed. The number of attached cells per unit area was quantitated from the photographs using a grid system. No significant differences could be detected between the numbers of cells attached to the 3 types of root surfaces studied on the individual roots or between any of the roots studied. Thus, initial attachment of HGF to diseased root surfaces is not inhibited by the presence of plaque or endotoxins.

Abstract
A large number of direct-bonding systems have been introduced for use by orthodontists. Although these agents are used for direct bonding of brackets to enamel, contact with skin, oral mucosa, and gingiva is not uncommon. While these products have wide clinical use, their biocompatibility has not been extensively investigated. The present study was undertaken to determine the effects of the primer component of Mono-Lok and the primer component of Control on gingiva. Three adult and one juvenile Macaca mulatta monkeys were used in this investigation. In two adults and the one juvenile animal, the primer component of Mono-Lok was applied to the right buccal surfaces of teeth; in the remaining adult animal, the primer component of Control was applied to the right buccal surfaces of teeth. The excess material was extended 5.0 mm onto the gingival tissues and for 3 minutes the cheeks and saliva were kept away from the sites to be tested. Saline solution was applied to the left buccal segments in all animals. Primer and saline solution were applied at 3-day intervals for a period of 21 days. The gingival tissues were examined clinically and biopsied for histologic evaluation. The gingiva in contact with the primer component of Mono-Lok exhibited pronounced inflammatory changes and was characterized by redness, swelling, and spontaneous bleeding. Histologic observations confirmed these findings by showing a marked inflammatory cellular response characterized by eosinophils. In contrast to these findings, the gingiva that was in contact with the primer component of Control or saline solution exhibited normal gingival architecture.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two hundred thirty-one inner city black teenagers, aged 14-17, were followed for two years to assess whether (1) their decision to deliver or abort a pregnancy differed from their perceptions of their mothers' attitudes about having a child or aborting a pregnancy, (2) satisfaction with the decision differed between the abortion and delivery groups, and (3) satisfaction with the decision was affected by who made the decision. Eight-one percent chose the pregnancy outcome that their mothers supported. Those who did decide without their mothers' support (19%) were divided equally between abortion and continuing the pregnancy. The majority in both groups were satisfied with the outcome decision, but initially more deliverers than aborters were satisfied. Satisfaction initially was related to who made the decision, but by the one-year follow-up the difference was no longer significant. Young teens do not seem likely to make a decision about pregnancy outcome that differs from their mothers' views; initial differences in satisfaction with the decision disappear over a one- to two-year period.

Abstract
Previous studies showed that the systemic administration of soluble gold salts resulted in significantly less periodontal destruction after 2 weeks of experimentally induced periodontitis. The present study compared the ultrastructural characteristics of the inflammatory lesion in animals receiving gold salts (experimental) with those in animals that had not received gold salts (control). Maxillary gingival biopsy specimens were obtained from the buccal aspect of ligatured teeth after 2 weeks of experimental periodontitis. A cellular and extracellular ultrastructural characterization was done in an "epithelial and superficial connective-tissue zone," and a "deep connective-tissue zone." Experimental (gold-receiving) specimens had an intact sulcular epithelium with narrow intercellular spaces overlying a collagen dense connective tissue. Control specimens had a degenerating disrupted epithelium overlying a collagen-poor connective tissue in which polymorphonuclear leucocytes predominated and often were closely apposed to morphologically altered fibroblasts. The cellular distribution of electron-dense deposits of gold salts was demonstrated, and their possible role in modulating mechanisms of cell cytotoxicity and collagen turnover is discussed.

Abstract
Systemic administration of gold salts for treatment of arthritis is thought to limit tissue destruction through alteration of inflammatory cell function. The present study ascertained if gold salts could modify the tissue destruction associated with an experimental marginal periodontitis. Therapeutic levels of serum gold salts were established in four squirrel monkeys (experimental) by intramuscular injection of Myochrisine (gold sodium thiomalate 25 mg/ml) at 5 mg/kg/body weight at 4-day intervals for 12 days. Marginal periodontitis was then induced around mandibular bicuspids by tying plaque retentive ligatures at the gingival margins. Periodontitis was induced around corresponding teeth in four control animals which had not received gold salts. Serum levels of gold salts were maintained in experimental animals, and all animals were killed 2 weeks after induction of periodontitis. Progression of periodontitis was evaluated histometrically on step-serial sections, and the results analyzed statistically. Specimens from gold-receiving animals had significantly smaller areas of infiltrated supracrestal connective tissue, and less loss of connective tissue attachment and coronal alveolar bone. Quantitation of total plaque around the ligatures showed no differences; however, there was less plaque located apical to the ligatures in gold-receiving specimens. Although the study design did not permit identification of the relative importance of cellular or microbial factors, it was concluded that administration of systemic gold salts was associated with significantly less periodontal destruction.

Abstract
A previous study showed that the systemic administration of soluble gold salts (gold sodium thiomalate) resulted in significantly less periodontal destruction after 2 weeks of experimentally induced periodontitis. In order to provide information on the possible mechanisms of action of gold salts in the experimental periodontitis situation, the present study analyzed and compared the characteristics of the inflammatory cell populations in animals receiving gold salts with those present in animals which had not received gold salts. Maxillary gingival biopsy specimens were obtained from the buccal aspect of ligatured teeth after 2 weeks of experimental periodontitis. Cell populations were characterized and enumerated, on 1-micron sections, in an epithelial and superficial connective tissue zone, and a deep connective tissue zone. Significantly fewer inflammatory cells were present in experimental (gold receiving) specimens, and this reduction was due primarily to fewer polymorphonuclear leucocytes (PMNs). No significant reduction occurred in any other inflammatory cell-type. The reduction in number of PMNs in experimental specimens was associated with a decreased number of morphologically altered, degenerating fibroblasts in the connective tissue compared to the PMN-dominated lesion of control specimens. Mechanisms whereby gold salts can reduce chemotaxis and functional capabilities of inflammatory cells are discussed.

Abstract
A 22-year-old black male was referred for periodontal therapy because of radiographic evidence of advanced bone loss associated with the posterior teeth. Clinical examination revealed gingivitis, normal sulcus depths, and minimal loss of clinical attachment. Complete blood counts, serum chemistry, and neutrophil function were within normal limits. Histological, histochemical and ultrastructural analysis of an extracted tooth revealed no loss of attachment; large areas of the cementum were collagen-poor and, ultrastructurally, resembled afibrillar cementum. It is proposed that the periodontal attachment mechanism present in this case was associated with a localized failure in normal periodontal development.

Abstract
DEAE cellulose anion exchangers having small ion exchange capacity (0.5 to 2.0 meq/g dry material) were tested for cell attachment kinetics and capacity to support growth anchorage-dependent cells. It was found that cells from established cell lines (BHK and MDCK) can grow to confluency on DEAE cellulose particles having exchange capacity of 1 and 2 meq/g dry materials, DE-52 and DE-53, respectively. On the other hand, chick embryo fibroblasts (primary cells) can grow only on DE-53 particles.
