Abstract
In recent years, there has been an increase in the use of antibiotics, primarily tetracycline anlogues, like minocy cline to treat rheumatoid arthritis. However, the mechanism of action of these analogues is not clearly defined. The present study investigates the effects of minocycline and tetracycline on some immunological parameters in Wistar rats and Swiss albino mice. Haemagglutination (HA) titre was employed as parameter of humoral immune response and % leukocyte migration inhibition (% LMI) and footpad thickness tests were used as measures of cell mediated immune response. Both minocycline and tetracycline significantly improved humoral immune response in rats as indicated by an increase in anti-SRBC antibody titre. In the LMI test, depending on the time period of drug administration, there was an increase or a decrease in the % LMI. When drugs were administered on days 1-7 after sensitization, both the compounds caused a significant increase in % LMI. However, the % LMI was significantly decreased when the drugs were administered on days 7-13 of sensitization, indicating variable effects of these agents on the Immune mechanism depending on the time of administration in relation to the development of immune responsiveness. Both minocycline as well as tetracycline produced a significant decrease in the paw volume in the footpad-thickness test which indicates a decrease in lymphokine production/release. The present study thus shows that minocycline and tetracycline exhibit immunomodulatory properties, which may contribute significantly to their beneficial effects in rheumatoid arthritis.

Abstract
In recent years, substantial evidence has accumulated to unambiguously implicate high plasma fibrinogen levels as a major cardiovascular risk factor. An open prospective and randomised pilot study was therefore undertaken in mild to moderate hypertensives to evaluate the effect of various antihypertensive drugs viz enalapril, felodipine and prazosin on the blood pressure and plasma fibrinogen levels. The systolic and diastolic blood pressures were determined at 0, 4 and 8 weeks whereas plasma fibrinogen assays were done at baseline and at the end of the 8th week of treatment in all the drug-treated groups. It was observed that although all the three drugs effectively controlled blood pressure, only enalapril significantly reduced plasma fibrinogen levels. Due to this additional effect, enalapril has potential to control two major cardiovascular risk factors--hypertension and high plasma fibrinogen levels--simultaneously.

Abstract
STUDY DESIGN A retrospective cohort study of tractor-driving farmers (study group) and non-tractor-driving farmers (control group) matched for age, gender, generic/ethnic group, land-holding, and work routines. OBJECTIVES To determine, using magnetic resonance imaging and clinical investigations, the effect of whole-body vibrations on the back in tractor-driving farmers. SUMMARY OF BACKGROUND DATA Low back pain and pathologic changes in the lower backs of tractor drivers have been reported. However, no study with a control group matched for work-related risk factors has been reported. METHODS Fifty tractor-driving farmers were compared with 50 non-tractor-driving farmers matched for age, gender, ethnic group, land-holding, and work routine. Both groups were interviewed for details of work routine, assets held, family profile, and vibration exposure to assess the influence of these parameters on signs and symptoms of backache. Magnetic resonance imaging was done to assess the effect of exposure on whole-body vibration and degenerative changes in the back. Vibration measurements also were done on tractors to observe the actual severity of the vibrations. RESULTS Regular work-related backache was more common among tractor-driving farmers (40%) than among non-tractor-driving farmers (18%, P = 0.015). Anthropometric evaluation showed abdominal girth and weight to be significantly higher in tractor-driving farmers (P = 0.006 and 0.046, respectively), whereas while height and arm span were similar between the two groups. Clinical examination for evidence of disc or facet degeneration showed no difference between the two groups. Evaluation of magnetic resonance images of tractor-driving farmers and non-tractor-driving farmers by an orthopedic surgeon, radiologist, and neurosurgeon showed degenerative changes to be similar between the two groups (P > 0.050). CONCLUSIONS Tractor-driving farmers report backache more often than non-tractor-driving farmers, but no significant objective differences on clinical or magnetic resonance imaging evaluation were found between the two groups.

Abstract
BACKGROUND Although in the past drug interventions were measured primarily on the basis of their efficacy and safety, today we are increasingly interested in what impact treatments have on the patient's day-to-day activities and quality of life. OBJECTIVES We sought to assess the effect of treatment with fluticasone propionate (FP) on functional status and sleep disturbances in children with asthma and to evaluate possible changes in the quality of life of the parents of these children after treatment. METHODS As part of a randomized, double-blind, parallel-group, placebo-controlled, multicenter study on the effects of FP powder (50 or 100 microg twice daily) on growth in children aged 4 to 11 years with mild-to-moderate asthma (n = 325), parents/caregivers completed the following questionnaires at baseline and at weeks 24 and 52 of treatment: Functional Status IIR (FSII), Sleep Scale-Children (SLP-C), and Quality of Life of Parents of Asthmatic Children (QOL-PAC). Change from baseline to weeks 24 and 52 within each treatment group was analyzed by using paired t-tests, and differences between treatment groups were analyzed by using analysis of covariance. RESULTS Mean FSII and SLP-C scores improved significantly over baseline values with either 50 or 100 microg FP at weeks 24 and 52 (p < 0.05) and were significantly better than scores in the placebo group (p < 0.05). In contrast, FSII scores at week 52 and SLP-C scores at weeks 24 and 52 decreased significantly in the placebo group (p < 0.05). QOL-PAC results revealed that scores on the Burden scale were significantly improved in both FP groups at weeks 24 and 52. Subjective Norms and Social scales improved significantly only in the 100 microg FP group at week 52. CONCLUSIONS The results of this study show that FP (either 50 or 100 microg twice a day) was associated with significant improvements in functional status and decreased sleep disturbances in children with asthma. In addition, treatment of children with FP was associated with a decreased burden on the parents of these children with asthma.

Abstract
BACKGROUND Inhaled corticosteroids are increasingly being used to treat mild-to-moderate asthma in children. However, data regarding therapy with this class of compounds, especially in children under age 6 years, is limited. Fluticasone propionate is a third generation inhaled corticosteroid with an optimal therapeutic index. Few large prospective clinical trials have been conducted to evaluate the efficacy and safety of fluticasone propionate powder in children. OBJECTIVE We sought to determine the efficacy and safety of fluticasone propionate powder administered by means of the Diskus and Diskhaler multidose powder inhalers in pediatric patients with persistent asthma. METHODS Fluticasone propionate powder (50 microg or 100 microg twice daily) or placebo was administered by means of the Diskus or Diskhaler inhalers to 437 children (4 to 11 years old) with persistent asthma for 12 weeks in a randomized, double-blind, parallel-group, multi-center trial. Patients were stratified according to whether they were receiving prior treatment with inhaled corticosteroids or cromolyn or beta2-agonists alone. RESULTS Fluticasone propionate powder administered by means of Diskus or Diskhaler significantly improved FEV1 (mean increase from baseline of 0.22 to 0.24 L; p < or = 0.023), clinic morning peak expiratory flow (mean increase from baseline of 48 to 55 L/min; p < or = 0.006), patient-measured morning (p < or = 0.001) and evening (p < or = 0.003) peak expiratory flow, and asthma symptom scores (in all but the 50 microg Diskus group; p < or = 0.036), as well as reduced albuterol use (p < or = 0.002) and nighttime awakenings (p < or = 0.019) at endpoint. Efficacy parameters were not significantly different between the two doses with either device. More placebo-treated patients discontinued the study because of lack of efficacy than patients in any fluticasone propionate group (p < 0.001). Fluticasone propionate did not suppress morning plasma cortisol concentrations and did not affect 24-hour urinary free-cortisol excretion. Adverse events were primarily pharmacologic effects of inhaled corticosteroids, and those related to the study drug occurred with low frequency. Patient satisfaction with both the Diskus and Diskhaler devices was high, with a majority of patients (> 80%) rating them favorably. CONCLUSION This study demonstrated that fluticasone propionate powder, at the conventional recommended doses of up to 200 microg/day administered by means of Diskus or Diskhaler, was well tolerated and improved lung function in children even as young as 4 and 5 years old regardless of whether they were previously treated with inhaled corticosteroids or cromolyn or beta2-agonists alone.

Abstract
Epidemiological studies were conducted in two phases each of 1 year duration in nine and 30 villages, respectively, in two northern states of India. Investigations were carried out to determine the causal factors, the activities involved and severity of injuries for farming and non-farming activities in tractor related accidents. A total of 76 cases involving five fatalities and 71 non-fatal injuries were recorded. The pattern of tractor related injuries in India have been found to be very different compared to those reported from highly industrialized countries. Fifty-four percent of tractor related injuries in the first phase and 49% in the second phase were because of non-farming activities. Of the total injuries recorded in both the phases only 1 and 6% were tractor related. A major cause of tractor related injuries were collisions. In the two phases 28 and 40% injured were passengers on tractor or trailer.

Abstract
To evaluate patient satisfaction with two breath-actuated powder inhalers (Diskhaler and Diskus), investigators asked patients to complete questionnaires as part of a randomized, double-masked, double-dummy, placebo-controlled study of fluticasone propionate powder (500 mg twice daily) in the treatment of chronic persistent asthma. At baseline, patients rated the importance of various inhaler attributes (i.e., ease of use, ease of loading with medication, ease of holding and operating, ease of cleaning, and ease of telling how many doses of medication are left). After 2 weeks of placebo and 6 and 12 weeks of active therapy, patients rated the inhalers on these same attributes. They also rated their general satisfaction with the inhalers and how comfortable they were using them. After 12 weeks, patients also rated the durability and convenience of carrying each device and were asked to indicate which they preferred. Data were available from 213 patients. All seven inhaler attributes measured were considered important by the majority of patients (71% to 91%), contributing to the validity of the patient-rated performance assessments. After 12 weeks of use, 57% to 88% of patients expressed a high level of satisfaction with the performance of the Diskhaler on all attributes; a high level of overall satisfaction (72%) and comfort (79%) was reported with this inhaler. Patients rated the performance of the Diskus inhaler very favorably, with 76% to 96% expressing a high level of satisfaction on all attributes; a high level of overall satisfaction (87%) and comfort (85%) was reported with this inhaler. At end point, 61.4% preferred the Diskus inhaler, 25.4% preferred the Diskhaler inhaler, and 13.2% expressed no preference. These breath-actuated powder inhalers may be acceptable alternatives to traditional metered-dose inhalers for the treatment of patients with asthma.

Abstract
Twenty patients of tuberculous meningitis (TBM) in age group of 6 months to 10 years included in the study were divided into two groups of 10 patients each. Rifampicin was administered in dosage of 10 mg and 7.5 mg/kg bw to each patient of groups I and II respectively. Drug concentrations in serum and CSF of these patients were measured by a microbiological tube dilution method using a strain of Sarcina lutea. In group I mean serum and CSF concentration was 3.84 micrograms/ml and 0.178 microgram/ml respectively, while in group II it was 2.16 micrograms/ml and 0.206 microgram/ml respectively. These concentrations were many times higher than the MIC against Mycobacterium tuberculosis. Mean percentage penetration of rifampicin in CSF was 5 and 10% in group I and II respectively. We recommend similar studies in large number of children before advocating the therapy with low dose of rifampicin in TBM.

Abstract
Because biological indicators alone do not adequately represent the comprehensive health status of a patient with asthma, we also assessed patients' health-related quality of life (HRQOL) in a randomized, double-blind, placebo-controlled study of the effects of the inhaled corticosteroid fluticasone propionate (FP). A total of 342 patients with moderate asthma were treated twice daily for 12 weeks with FP powder (50, 100, or 250 micrograms) or placebo. At regular intervals, patients completed the Medical Outcomes Study Short Form-36, acute version (SF-36A), a general health status questionnaire measuring eight dimensions of HRQOL; the 20-item Living with Asthma (LWA-20) questionnaire, a disease-specific instrument measuring HRQOL; and three additional questions related to sleep loss and number of nighttime awakenings. Each of the three FP groups compared with placebo had significantly higher scores at study endpoint on the Physical Functioning (p < 0.001) and Role-Physical (p < or = 0.0001) dimensions of the SF-36A; the FP 100- or 250-micrograms groups compared with placebo also had significantly higher scores on General Health Perceptions (p < 0.03), Vitality (p < 0.007), and Mental Health (p < 0.02). At endpoint, all three FP groups compared with placebo had significantly better scores on the LWA questionnaire (p < 0.05) and on the sleep-related items (p < 0.0001). These data, collected using both a general health status questionnaire and an asthma-specific questionnaire, demonstrate that fluticasone propionate powder can improve HRQOL in patients with mild-to-moderate asthma.

Abstract
A preliminary study of anti-phenolic glycolipid-I (PGL-I) IgM antibody detection using M. leprae gelatin particle agglutination (MLPA) test kit is described. Antibodies were demonstrated in 70% of our leprosy patients taking antileprosy treatment. The percentage of positivity of multibacillary cases was 86.0, whereas that of paucibacillary cases was 30.0. Good correlation was found between bacteriological index and the presence of antibodies. Antibodies were detected in 28% of our patients released from treatment. Fourteen out of 27 household contacts were found to have antibodies but none of the normal controls were seropositive. These preliminary data demonstrate that MLPA test is not applicable as sero-diagnostic test or as a test of cure, but may be useful for epidemiological studies and as a research tool.

Abstract
MURCS association (Mullerian hypoplasia/aplasia, renal agenesis and cervicothoracic somite dysplasia) is emerging as the second most frequent cause of primary amenorrhoea after Turner syndrome. Seven cases have been described and analysed. All cases had absence of uterus and tubes 85% had cervical spine abnormalities such as vertebral fusion, hypoplasia of vertebrae or butterfly vertebrae and short stature and 28% had renal agenesis or ectopy. The latter finding is in contrast to the reports in world literature where the frequency of renal agenesis is higher. There was no familial incidence in these seven cases lending credence to the belief that the association is essentially sporadic.

Abstract
OBJECTIVE There is a paucity of information in the literature regarding the type of reference sources that are used by community pharmacists to answer drug information questions. This survey was conducted to determine the frequency of use of selected drug information references by independent and chain pharmacists in Louisiana. DESIGN A study population of 15% of registered pharmacists was obtained by random stratification of all pharmacists on the mailing list of the Louisiana Board of Pharmacy on the basis of zip code and gender. These pharmacists were mailed an uncoded, pretested questionnaire and were asked to complete and return it if they were employed by an independent or chain pharmacy; nonchain and independent pharmacists were asked to return their questionnaires uncompleted. No follow-up was performed. PARTICIPANTS Ninety-one independent pharmacists (mean age=45 y; mean years of experience=21) and 71 chain pharmacists (mean age=40 y; mean years of experience=16). OUTCOME MEASURES The frequency of use of selected drug information reference sources by independent and chain pharmacists and the type of drug information questions received by pharmacists were determined. A Statistical Analysis System software program was used to analyze the data. Spearman's rank test was used to determine statistical differences between independent and chain pharmacists. The a priori level of significance was p less than or equal to 0.05. RESULTS A 54% response rate was obtained.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two large field studies were conducted to test the validity of the Job Severity Index (JSI) as an engineering tool for the control of manual materials-handling injury. Comparisons were made between the calculated JSIs of 453 individuals working in 101 different jobs and the injuries sustained by the same individuals over a period of 1057881 exposure hours (529 exposure years). The results revealed the existence of a job severity threshold above which the incidence, severity, and cost of injury dramatically increased. It was concluded that the JSI method can effectively be used to control injuries caused by the manual lifting of loads.

Abstract
A single dose of 80 mg racemic propranolol hydrochloride was administered by mouth to six healthy male volunteers. The mean concentration achieved in seminal plasma at 2 h after dosing was almost identical to that in blood serum. The concentrations of propranolol in seminal plasma and saliva were much less than those known to reduce sperm motility by 50% in vitro. The concentrations in saliva did not reflect those in blood serum. Propranolol in the dose administered in this study is unlikely to affect fertility by its presence in saliva or semen.
