The efficacy of the antiviral agent Amantadine (AM, 5-100 mg/kg/sc, ip or intrahypothalamically, 12.5-100 micrograms bilaterally) in influencing body weight and food intake in drug-free rats, and in preventing neuroleptic-induced weight gain, was assessed in adult female rats. In drug-free rats, acute administration of systemic AM or directly injected in the lateral hypothalamus (LH) displayed a significant dose-dependent anorectic effect (p < 0.001). This effect could be mediated by the brain monoaminergic system, because systemic or local injections of AM increased dopamine and serotonin overflow in the nucleus accumbens and in the LH. Chronic administration of AM significantly decreased body weight gain in drug-free rats only at the dose of 100 mg/kg/sc. Similarly, obesity induced by the neuroleptic drug sulpiride (SUL, 20 mg/kg/ip for 21 days) was prevented by AM only at the dose of 100 mg/kg. AM did not prevent SUL-induced hyperprolactinemia, disruption of the vaginal cycle and a decrement in the weight of the uterus and ovaries at any dosage. This lack of efficacy of AM contrasts with that of bromocriptine, which completely prevented SUL-induced weight gain and hyperprolactinemia. The results show that despite a potent acute anorectic effect, AM displays a weak antagonistic action on SUL-induced obesity in rats, in contrast to the preliminary results obtained in humans. As AM metabolism differs in humans and rats, additional research is needed before its systematic testing in counteracting neuroleptic-induced obesity in patients with mental disorders.

The high prevalence of obesity in our society makes obesity a major and increasing health hazard. Extensive observations pointed out a connection of obesity with a variety of illnesses. The evidence shows that obesity is a major contributor to the high prevalence of cardiovascular diseases, diabetes, hypertension, dyslipidaemia, gallstone disease, osteoarthritis and hyperuricaemia in the general population. Obesity also appears to be a contributor to cancers of the colon, prostate and rectum in men and breast, ovary, uterus and biliary tract in women. Hormonal abnormalities tend to occur in both obese men and women. Obese women have menstrual irregularities more often than nonobese. Obese persons tend to have reduced pulmonary function compared with nonobese. Although there are many unresolved issues, weight control is necessary for avoiding and reducing health implications of obesity. More information is required for controlling obesity and its consequences, prior to recommending a dietary advice and treatment.

Endoscopic techniques were used to ovariohysterectomize two hybrid Asian lions (Panthera leo) in order to reduce the risk of postoperative wound complications associated with standard surgical techniques. One of the lions was aged, overweight, and considered an anesthetic risk. The animals were anesthetized, intubated, catheterized intravenously, and placed in dorsal recumbency with the head lower (Trendelenburg position). Ventilation was assisted mechanically. Following abdominal insufflation, a surgical trocar was placed in the abdominal cavity. Two additional 12-mm surgical trocars were placed under direct visualization using a videoscope. The ovaries and uterus were removed endoscopically, and the abdominal cavity was inspected for hemorrhage under decreased insufflation pressure before closure. The surgery was complicated by obesity, by uterine enlargement from cystic endometrial hyperplasia and endometrial polyps, and by ovarian enlargement and fragility because of bilateral cystic rete ovarii. The procedure and anesthetic recovery were uneventful. Postsurgical recovery time and convalescence lasted less than 3 days, and the animals were reintroduced to an exhibit mate and placed on exhibit within 8 days. The technique is appropriate for use in lions, even those with pathologic reproductive changes, in zoos.

Dysfunction of various hypothalamic systems may be the basis of a number of symptoms in Prader-Willi syndrome. The often abnormal position of the baby in the uterus at the onset of labour, the high percentage of infants with asphyxia and the high proportion of children born prematurely or post-maturely may all be related to abnormal fetal hypothalamic systems, as the fetal hypothalamus plays a crucial role in labour. Abnormal luteinizing hormone-releasing hormone neurones are thought to be responsible for the decreased levels of sex hormones, resulting in non-descended testes, undersized sex organs and insufficient growth during puberty. A lack of growth hormone-releasing hormone may also contribute to the short stature of patients with Prader-Willi syndrome. In addition, the aberrant control of body temperature and daytime hypersomnolence may result from hypothalamic disturbances. The number of oxytocin neurones--the putative satiety neurones--in the hypothalamic paraventricular nucleus is markedly decreased in Prader-Willi syndrome. This is presumed to be the basis of the insatiable hunger and obesity of patients with the syndrome.

The indications and contraindications for simultaneous surgical correction of the diseases of hepato-biliary system remain unclear and debatable. 308 patients at the age of 20-78 years have been operated on liver, biliary tract in combination with surgery on other organs. More than 600 operations have been performed. The rate of morbidity was 1.6% lethality-2.3% (7 patients). The risk of death was increased for patients over 60 years of age, who had urgent combined operations. The optimal operative access and drainage were of a special importance. Intramuscular Heparin injections in the dose of 5000 units 4 times a day were used in patients over 60 years of age and in case of 3d or 4th degree of obesity. Liver and biliary tract surgery was combined with resection of the stomach, hernioplasty, appendectomy, echinococcectomy, hemicolectomy, nephrectomy, thyroid gland's resection, amputation of the uterus, sectoral resection of the buast and others. Endotracheal anesthesia was used in all the cases.

The lack of uniformity in the nomenclature of the uterine sarcomas, it have contributed to a variety and variability of classifications. Fortunately the sarcomas of uterus are rare. The incidence of this tumor is of 3-5% of all the uterine cancers or of 1.7/100,000 women of 20 years or more. The clinical presentation of these tumors is diverse could come bleed uterine abnormal, abdominal pain, pelvic mass, discharge or cervix prominent mass. Clinical discoveries associated with exist the sarcomas how they are the obesity and high blood pressure in a 30% of the patients it are also observed antecedents of pelvic radiation in a 5-10% of the cases. The genomic alterations that is reported the chromosomes in the literature is associated with 1, 7 11 playing an important paper in the initiation or progression of the sarcomas. We was carried out a retrospective analysis of 37 cases of uterine sarcoma managed in the National Institute of Cancerology at one time of 5 years. Being that the leiomiosarcomas comes in the 51.3% of the cases, followed by the stromal sarcoma, bleed uterine abnormal it was the clinical fact of high importance, detecting these patients in Ia and IIa stadiums predominantly. We observed an increment in the incidence of the uterine sarcoma in patients of 40 years or more. 17 patients were managed exclusively with surgery, 17 patients with surgery and radiotherapy and 5 patients with surgery and chemotherapy (2 patients were managed with surgery + radiotherapy + chemotherapy). The index of failure was from the 45.1% to two years in general form, coming metastasic illness in lung, liver and breast mainly. In conclusion, the adjuvant radiotherapy and chemotherapy to the hysterectomy doesn't increase the index of survivor in the several subtype of uterine sarcomas.

Leiomyosarcoma are malignant tumors showing smooth muscle differentiation, they are rare, representing only about 25 percent of all uterine sarcomas and mixed malignant tumors and slightly more than 1 percent of all corporeal malignant tumors. Usually they arise in postmenopausal women and are not known to be related to the known risk factors for endometrial carcinoma (nulliparity, obesity, diabetes mellitus, hypertension, etc.) or carcinosarcoma (prior radiation therapy). They may occur in uteri that also bear typical benign leiomyomas, but leiomyosarcoma rarely can be proven to have arisen in or from benign leiomyomas. We report on two premenopausal women with leiomyosarcoma--out of totally 31 cases in our clinic from 1975-1995 who got pregnant after surgical treatment preserving the uterus. The patients are alive without evidence of disease 3 and 6 years after surgical resection.

This is a retrospective observational study of outcome of 11 cases of vaginal hysterectomy for undescended and enlarged uterus carried in University Hospital, Kuala Lumpur. The cases included relative contraindications such as 14 weeks size fibroids, severe obesity, previous Caesarean section and nulliparity. All the eight patients agreeable for prophylactic bilateral salpingoophorectomy had their ovaries removed. Operative time ranged from 1 hr 20 min to 2 hr 15 min. All patients were sent home within 48 hours of the operation. The excellent outcome of our initial experience highlights the known advantages of vaginal hysterectomy for undescended and enlarged uterus.

Targeted disruption of the receptor for glycoprotein hormone, FSH (FSH-R) causes a gene dose-related endocrine and gametogenic abnormality in female mice. The resulting FSH-R knockout (FORKO) mutants have disordered estrous cycles, ovulatory defects, and atrophic uterus. The heterozygous animals that initially show reduced fertility undergo early reproductive senescence and stop breeding altogether. Lack of FSH-R signaling in females causes severe ovarian underdevelopment producing chronic estrogen deficiency. This was accompanied by increases in serum testosterone levels. Ovarian aromatase gene transcription and translation are unaltered in the mutants. Early loss of estrogen in the null mutants leads to obesity and skeletal abnormalities that intensify with age producing (kyphosis), a hunchback appearance. Both these changes also become apparent in older heterozygous mice coincident with early reproductive senescence. The expression of nuclear estrogen receptor(s) alpha and beta genes and the corresponding proteins in the ovary and uterus of FORKO mice appear to be intact. The loss of ovarian estrogen creates an imbalance in A and B forms of the progesterone receptor in the uterus of both heterozygotes and null mutants. Some of the changes we have documented here in FORKO mice are reminiscent of the ovarian dysfunction and other major symptoms that are usually associated with estrogen deficiency. In null mutants, estradiol-17beta administration promptly induced uterine growth and reversed the accumulation of adipose tissue indicating that estrogen receptors are functional. Thus, the phenotypes evident in these genetically altered FSH-R mutants may provide an experimental system to explore the effects of estrogenic compounds on different targets including the ovary in a nonsurgical setting.

The nationwide survey of institutions with MHTS and human dry dock capabilities was analyzed and the following results have been obtained. 1) The relative rates of cancer detection by sex and organ were the stomach > colon > rectum > lung > kidney > esophagus for men and the stomach > breast > uterus > colon > thyroid > lung for women. 2) Gastric cancer takes first place in the ranking of rates of cancer detection in the population of both sexes, followed by colon cancer. The difference in rate of detection between these cancers has been narrowed from year to year. In 1997, the ratio of gastric to colon cancers was 10:7. 3) Early cancers account for 74% of gastric cancer patients and 75% of colon cancer patients. 4) Since gastric and colon cancers are detected early, the proportions of persons with gastrointestinal symptoms are as low as 28% for gastric cancer patients and 26% for colon cancer patients. 5) The relative rates of cancer detection by the degree obesity are normal > obese > lean person. The rates of gastric and colon cancers are 2- and 3-fold higher for obese persons than for lean persons, respectively. Gastric and colon cancers are detected with higher frequency in well-nourished persons. The present review of the national MHTS and human dry dock statistics has confirmed the efficacy of MHTS and human dry dock, especially in the examination for gastrointestinal cancers.
