Abstract
19653 Background: Malignant diseases have a strong influence in quality of life, being sexuality one of the most affected variables. The objetive is to determine the prevalence of sexual dysfunction in a cohort of patients with cancer and its relationship with the following: pain, fatigue, nausea, vomiting, mechanisms of adaptation to stress, anxiety and depression. Methods: Anonymous questionnaires were used, including: treatment, adverse events, Zimong and Snaith depression and anxiety scale, sexual dysfunction questionnaire, coping strategies of Tobin David, Hopwood body image scale and the analogical visual test for pain evaluation. Results: Between January and August 2006, sixty four patients were evaluated; 72% were women; median age: 50 years old. Libido was absent in 50%; this was associated with gender (better in men; p=0,05) and the presence of pain (p=0,05) and fatigue (p=0,05) but not with age. All patients who had intact libido also had arousal and orgasms; this was more prevalent in men than in women and in subjects younger than 60 years. Arousal was absent in 47% of cases. Forty four percent of men had erectile dysfunction; this was present in all patients older than 60 years. Frequency of intercourses was decreased in 75%. Fifty eight percent of patients said that their sexuality was better before the diagnosis of their disease. Interestingly, 85% didn’t talk to their doctors about their sexual problems. Conclusions: One out of 2 patients had sexual dysfunction, predominantly women. Sexuality was affected mainly by pain and fatigue. Although normal libido was present in all ages, subjects older than 60 years had less arousal and orgasms. No significant financial relationships to disclose.

Abstract
17530 Background: Preservation of hematopoietic cells (HC) is usually achieved by storing cells in liquid nitrogen at - 1960C (Cryopreservation) (CP). We aim to: observe how many leukapheresis (LK) were necessary in order to obtain the minimal number (n°) of HC (CD34+/kg) for a proper engraftment (EG); correlate the n° of cryopreservated and infused cells with the time of EG; determine if the time of CP at -800C influences the time of EG; determine if the pre-transplant (PT) condition (partial or complete remission) plays a role in the time of EG and/or the time of hospitalization of the patients (pts). Methods: This was a retrospective study. We included all pts that received autologous transplant which HC after CP in our institution between September 2004 and August 2006. Qualitative results were analyzed by Fischer exact test and relation between qualitative and quantitative results by Mann-Whitney/Wilcoxon two- sample test (Kruskal-Wallis test for two groups). Results: 27 pts were included (N=27); the average age was 48.3± 16.6 years with a range of 64 (4–68) years. Diagnosis included: Multiple Myeloma 40%, NHL 22%, Hodgkin disease 15%, AML 15%, Amyloidosis 4%, and Ependymoma 4%. In 66.7% of the pts only one round of LK was needed for recollection. The CP time at -800C had a range of 113 (8–122) days. The median time for EG was 11 days for neutrophils (nt) and 17 days for platelets (pl). There was not significant correlation between PT condition and: n° of nt before or after day 11 (p=0.515); n° of pl before or after day 17 (p=0.972); hospitalization time (p=0.55); time for EG of nt (p-0.553) and pl (p=0.936). There was a significant difference between receiving =5x106 CD34+/Kg and pl EG time before day 17 (p=0.01) but not for nt EG time (p=3.83). CP time had no significant difference in relation to the pl EG before or after day 17 (p=0.08) or nt EG before or after day 11 (p=0.49). Conclusions: The majority of pts had a proper CD34+/Kg count with one LK round. Doses =5x106 CD34+/Kg were associated with less time for pl EG. The storage of HC at -800C showed to be safe for periods between one week and 4 months. The time of storage at -800C did not seem to affect the time of EG but showed a trend towards slowing pl recovery. The PT condition did not correlate with the time for EG or the hospitalization time. No significant financial relationships to disclose.

Abstract
The metabolization of DL-methionine and a hydroxy analogue form, DL-MHA-Ca, was studied by means of 14C-labelled substances. For this purpose 60 male day-old chicks were administered 1-14C-labelled substances DL-methionine and DL-MHA-Ca into the birds' crop. In 20 birds the 14CO2 activity excretion with the expired air was measured for a period of 24 hours post administration by means of radiorespirometry. The birds were killed 24, 48 and 72 hours post administration and the 14C-activity determined in the following fractions: excrements, gastrointestinal contents, digestive tract, blood, kidney, liver and gallbladder, lung, heart, spleen, leg and breast muscles and the residual fraction. Over the experimental period as a whole 17.0% of the administered dose was recovered in the excrements of the 1-14C-DL-MHA-Ca labelled birds and 4.4% in the 1-14C-DL-methionine treated birds. The maximum 14CO2 excretion in the expired air was reached after 1.5 hours, irrespective of whether 1-14C-DL-methionine or 1-14C-DL-MHA-Ca had been administered. Within 24 hours post administration, 15.8% of 1-14C-DL-methionine were excreted as 14CO2 via the lungs, as against 11.4% following application of 1-14C-DL-MHA-Ca. While no significant differences between the groups were recorded for the 14C-incorporation of the liver, the kidneys generally contained a higher 14C-activity after the administration of 1-14C-DL-methionine than after 1-14C-DL-MHA-Ca. The relative incorporated 14C-activity was distributed in the following proportions: 25% in the leg and breast muscles, about 25% in the remaining organs and about 50% in the residual fraction. The 14C-activity found in the protein of the leg and breast muscles was separated by thin layer chromatography and recovered exclusively in methionine. The 14C-activity in the lipids of the leg and breast muscles accounted for only a very small proportion of the total incorporated 14C-activity. Irrespective of the adaptation diet, the rate of incorporation of 14C into the birds' body was found to be higher after administration of 14C-DL-methionine than after 1-14C-DL-MHA-Ca.

Abstract
Recombinant granulocyte colony-stimulating factor (rhG-CSF) has been shown to hasten granulocyte recovery after autologous BMT. In current protocols, rhG-CSF treatment starts 1 day after BM reinfusion. Our study retrospectively examined the effects on haematological recovery of a day 6 delayed administration. Seventy-eight patients receiving autologous BMT for malignant lymphoma (21 non-Hodgkin's lymphoma and 9 Hodgkin's disease) or solid tumors (33 breast carcinoma and 5 ovarian carcinoma) were split up into three study groups. Two groups receiving a 5 micrograms/kg/day of rhG-CSF starting either 1 day (day +1 group, n = 25 patients) or 6 days (day +6 group, n = 24 patients) after BM reinfusion were compared with 29 historical control patients. Granulocyte recovery to 0.5 x 10(9)/l was 12 days in day +6 and day +1 groups versus 16 days in control group (p < 0.005) without any difference in other hematological parameters, infectious complications or length of hospitalisation between the three groups. The day +6 administration allows elimination of a median of 7 days rhG-CSF. It has been concluded that the day +6 administration gives the same clinical benefit as day +1 administration with consequent cost reductions.

Abstract
Dental x-rays were taken of isolated and in situ adult molar teeth of the Krapina Neandertal (n = 63) and of recent and contemporary molars (n = 423). The radiographs were digitized at high resolution (1,024 x 1,520 x 8 bits) with a 35 mm solid state scanner. Ratios of enamel cap area to the underlying dentinal-pulpal area were determined and comparisons were made between average ratios for the Neandertal and contemporary molars. Neandertal molars had significantly smaller ratios than did contemporary teeth (P < 0.05). It is suggested that the smaller ratios represent relatively thinner enamel for Neandertals and that the thin enamel may have been caused by a metabolic depression that resulted in reduced enamel quantity (hypoplasia). Alternatively, the observed differences may be related to expanded pulps seen in various stages of taurodontism.

Abstract
Monoclonal antibodies (MAbs) were prepared against native cytochrome f (cyt f) isolated from turnip leaves. The two MAbs obtained, designated MAb-JB2 and MAb-ED4, were Western blot positive to purified turnip cytochrome f and also reacted with inside-out (ISO) but not right-side-out (RSO) spinach thylakoid membranes. MAb-ED4 reacted with a covalent adduct formed by crosslinking cyt f and plastocyanin (PC), whereas MAb-JB2 did not. In contrast, MAb-JB2 reacted with the isolated cyt b6/f complex but MAb-ED4 did not. These results indicate that MAb-JB2 binds to cyt f at or near the PC binding site on f, whereas MAb-ED4 binds to a portion of cyt f which is not exposed in the cyt b6/f complex. The location of the epitopes in the primary sequence of cyt f was determined by trypsin hydrolysis, HPLC separation of tryptic peptides, and ELISA identification of the purified peptides. The molecular weights of the purified peptides, determined by gel exclusion chromatography, were found to be 5040 and 3130 Da for MAb-JB2 and MAb-ED4, respectively. Amino acid sequencing showed that the first eight amino acids of the MAb-ED4 positive peptide were L-D-Q-P-L-T-S-N. These results suggest that the 3130-Da peptide has 28 amino acids extending from Leu 223 to Arg 250. This peptide is located on the N-terminal (lumen) side of the postulated membrane-spanning sequence. The first eight amino acids of the MAb-JB2-positive peptide were N-I-L-V-I-G-P-V. This sequence and the peptide molecular weight indicate that the epitope for MAb-JB2 is located within a 44-amino acid peptide extending from Asn 111 to Arg 154.

Abstract
The rapid rate of tooth wear frequently reported among certain contemporary aboriginal populations has often been attributed to dietary form and abrasives. Several investigators have reported a close correlation between food bulk and the wear planes formed over the dental arches, i.e., steep oblique wear vs. flat horizontal planes. In this investigation we demonstrate that arch shape is an additional and a significant factor influencing the distribution of wear facets and exposed dentin over occlusal surfaces. We examined 64 dental stone casts of Aboriginals from Yuendumu, Central Australia, born between 1900 and 1940. These casts offer a record of the variety of tooth wear and arch forms and their interrelationships. This group of individuals, some subsisting on abrasive and some on soft diets, have dentition which exhibit various wear rates and wear patterns probably due to the diversity of arch shape, size, and occlusal relationships. Hypsiloid or U-shaped maxillas had a more buccally directed wear in contrast to the parabolic or hyperbolic forms, which exhibit a heavier lingual loading. Varying occlusal conditions also contribute to differing wear patterns over the arches. Individuals with alternate intercuspation, for example, have a more horizontally directed wear. These and other conditions of shape, size, and occlusion emphasize the importance of morphological factors in the production of tooth wear rates and patterns in addition to dietary abrasives.

Abstract
Interproximal grooving was recorded in 85 nineteenth century aboriginal skulls from Swanport in South Australia. One or more grooved teeth were noted in 41% of individuals, but the frequency of grooving in males was twice that in females. Distal surface grooving was noted in 93 teeth in contrast to only five instances of mesial grooving. The lesions were similar in appearance to those reported in many other populations--confined primarily to the premolar-molar region, located at the cementoenamel junction, directed horizontally, and usually clean-cut and free of caries. Stripping of animal sinews between the clenched posterior teeth has been recorded on film as a common task activity in traditional aboriginal society. In our opinion, task activity and not toothpicking was the likely cause of the observed interproximal grooving in the aboriginals.

Abstract
The study of tooth wear among prehistoric and recent populations has frequently been concerned with the rate and pattern of wear over the dental arches. In this report we considered the question of tooth wear variation among collections of Australian Aboriginal crania recovered from several sites along the Murray River in Southeastern Australia. These crania represent the remains of relatively recent populations from about 2,000 years ago until the early 19th century. The degree of tooth wear for each dental arch was recorded by an established method of determining the ratio of exposed dentin. The pattern or distribution of wear over each arch was summarized by principal component analysis. The mean wear degree and pattern were compared among four geographical grouping of crania separated by up to 700 miles of river frontage. Our results showed, as expected, a significant difference between the well-defined population at the Lower Murray site (Swanport) and the three upriver groups. However, there were significant differences among these three collections as well. Sexual dimorphism was noted but was only significant in the Lower Murray group; the mean wear was greater and also more variable among the males. At the second of the Middle Murray sites the pattern of wear was different and the degree of wear was significantly less than in the other groups. A possible explanation for this diversity may be environmental and subsistence base differences. The evidence from the Lower Murray supports this possibility, but the differences among the other three groups are not as clearly established. However, our results do suggest that the Murray Black collection, from which these crania were obtained, may not be as homogeneous a group as previously believed.

Abstract
Our objectives were to determine how the prevalences of caries in elementary school children vary between geochemically defined regions of the state of Missouri and to compare this variation with that found for prehistoric Missouri inhabitants (Hildebolt et al.: Am. J. Phys. Anthropol. 75:1-14, 1988). Caries data on 6,584 school children were used in the study of second and sixth graders drinking optimally and suboptimally fluoridated water. Geochemical regions were based on maps recently published by the United States Geological Survey. Differences in mean caries scores and proportions of children with caries were tested by analysis of covariance, analysis of variance, Student t, and chi-squared tests. We found that caries prevalences do vary between the geochemical regions of the state. In the total sample, however, there were no significant differences between those children drinking optimally fluoridated water and those drinking suboptimally fluoridated water. We conclude that there is variation in caries rates among geochemically defined regions of the state and that geochemical factors associated with young parent materials may be antagonizing the action of fluoride.

Abstract
The possible implications of variations in dental attrition patterns have necessitated a detailed assessment of the types, ranges, and causes of tooth wear. Hear we employ measurements of postcanine occlusal wear facets from a sample population of extant Australian aborigines. A principal components analysis was applied as a tool in determining common types of attritional patterns. It was concluded that the range of intrapopulational variation in dental wear patterns must be attributed to a multiplicity of sources in addition to such commonly cited causes as dietary variations, gender, age, and developmental eruption sequences.

Abstract
The ability to describe dental arch shape is necessary for biomechanical studies of occlusion as well as for anthropological studies of human and primate dental variation. A mathematical method of describing and classifying human dental arch shape was used to assess the nature of individual variability. The method involved the calculation of a series of third-degree polynomials which were fitted to coordinate points along the dental arcade. The slopes of the polynomials, evaluated at these coordinate points, provided a multivariate description of shape, independent of arch size. Graphic representations of arch shape could be constructed from the polynomial equations. These mathematical techniques were used in association with multivariate and univariate statistics to explore the types of variability in dental arch shape among a population of Australian aborigines. The results illustrated the ambiguities of conventional subjective classifications.

Abstract
In previous epidemiological studies, it has been suggested that geochemical factors besides fluoride may affect the prevalences of dental diseases. Our objective in this study was to determine whether the prevalences of periodontal diseases, coronal caries, and root caries for prehistoric inhabitants vary between geochemical regions of the state of Missouri. Burial sites were located on unique maps that depict geochemical variation among regions of the state. Data on dental caries and alveolar bone loss were gathered from 179 of the best preserved skeletal remains of the Late Woodland (A.D. 400-900) and Mississippian (A.D. 900-1700) periods. Mean caries scores and proportions of individuals with caries were calculated for these geochemical regions. Average alveolar bone loss was regressed on age for the individuals of these regions. Significant differences in caries and bone loss were found between several regions. These differences cannot be adequately explained by fluoride concentrations or by diet. It is suggested that geochemical factors, in addition to fluoride, may have affected the prevalences of dental diseases.

Abstract
The incidence of dental disease among people in developing countries today raises questions about the variation in the oral health of prehistoric populations. Considering these questions, we offer observations describing several types of dental disease which occurred among certain prehistoric populations of Hungary. The dental remains of 162 individuals recovered from seven sites of the Neolithic, Copper, and Bronze Age periods were examined for evidence of caries, hypoplasia, and periodontal disease. Appropriate methods were used to describe and record these dental lesions. The incidence of dental caries was low by comparison to other prehistoric agriculturists except for two forms of root caries: cervical and cemental. These types accounted for 68% of all the carious teeth recorded. Enamel hypoplasia was also lower than expected, occurring on only 4% of the total number of teeth. Periodontal abscesses were rare but other milder forms of periodontal lesions were frequent. Alveolar bone resorption occurred in varying degrees and followed the expected age distribution. The few exceptions were children or adolescents whose crania had other lesions suggesting a mineral metabolic disturbance. The lower incidence of enamel caries is likely due to high fluoride ingestion which also may have influenced the expression of enamel hypoplasia. No clear population trends were seen in dental disease incidence except for cemental caries which were found among Copper and Bronze Age remains.

Abstract
In a balance trial with 10 pigs (mean body mass 50 kg) the influence of a bacterial protein supplement (Alcaligenes eutrophus) on N-metabolism was investigated. The bacteria were included into the diet at levels of 7 and 14% at the expense of extracted soyabean meal. Thus bacterial "pure protein" (bacterial non-nucleic acid N X X 6.25) amounted to 30 and 60% of the protein of the ration. Consuming 2 kg of feed dry matter per day the animals of the control group (I) and the experimental groups (II and III) ingested 48 g, 52 g and 55 g of total N respectively. The difference in N-intake is explained by the additional nucleic acid-N, amounting to 19,8% of total bacterial N. Daily weight gain (on average 1054 g) and feed conversion efficiency (feed ingested/weight gain; on average 1,9) were relatively improved at the highest dietary level of bacterial cell mass. Faecal N-excretion was increased significantly, whereas renal N-excretion remained unchanged. Mean apparent N-digestibility was 87,4% showing no significant difference between the experimental groups. N-balance values were noticibly increased following the intake of the bacterial protein supplement. The excretion of urinary urea-N was slightly reduced whereas 4-6 times as much allantoin-N was excreted when bacteria were fed. It is calculated that about 80% of the bacterial purines are renally excreted as allantoin and uric acid.
