Department of Morphology, Faculty of Veterinary Medicine, Ghent University, Merelbeke, Belgium.
In this study the endometrial morphology of four dogs in oestrus and 10 dogs in late metoestrus was investigated with scanning electron microscopy. In early oestrus the cells were slightly convex with fairly long microvilli and cell boundaries that were apparent but situated on a deeper level than the cell surface. In late oestrus the cells were clearly convex with long and numerous microvilli masking the cell boundaries. At the beginning of late metoestrus the cells became less convex with many but short microvilli and prominent but lower situated cell boundaries. At the end of late metoestrus the cells were flat with very short microvilli and protruding cell borders. These morphological findings were correlated with the cyclic variations of the steroid hormone levels.

CONTENTS: Cystic endometrial hyperplasia (CEH) was experimentally reproduced by the intraluminal insertion of a silk wire in the uterus of metestral bitches to obtain a model for the study of spontaneously occurring CEH in the bitch. This mechanically reproduced CEH corresponded histologically very well to spontaneously occurring CEH. With respect to sex hormone receptor expressions, however, there was no similarity. In the mechanically induced CEH, progesterone receptor expression was reduced in the epithelial cells (surface epithelium and endometrial glands) and slightly increased in the stromal fibroblasts and myometrium as compared with the normal metestrus uterus. The oestrogen receptor expression in mechanically induced CEH was reduced in the epithelial cells (surface epithelium and endometrial glands) and more or less unchanged in the stromal fibroblast and myometrium as compared with the normal metestrus uterus. This is in contrast to the increased sex hormone receptor expressions in all uterine cell types, observed in spontaneously occurring CEH. The mechanically induced CEH model corresponds immunohistochemically more to early placentation and to pyometra in the bitch. Thus this experimental CEH model is not suitable for pathogenic studies of spontaneously occurring CEH in the bitch.

OBJECTIVE: To prospectively assess bone density and the factors determining the rate of bone loss over a 10-year period of postmenopausal life. DESIGN: Prospective, observational study. METHODS: One hundred and four normal White postmenopausal women, baseline mean age 59 years (range 47-71 years) completed the study (mean duration of follow-up 10.2 years, range 9.4-10.6 years). None had diseases or were taking medications affecting bone metabolism at entry to the study. Information was collected on medical, fracture and smoking history, alcohol use, dietary calcium intake and physical activity. Body composition and bone density were measured by dual-energy X-ray absorptiometry at baseline and at 10 years. Biochemical, haematological and hormonal analyses were performed. RESULTS: Twenty-four percent of the women started hormone replacement therapy (HRT) during the study period; most of these remained on therapy at follow-up. The mean duration of therapy was 6.6 years (range 2.8-10.4 years). The use of HRT was associated with significant gains in bone density (total body + 3.0%, trochanter + 4.2%, Ward's triangle + 4.4%, spine + 10.5%) and a significant reduction in vertebral fracture risk [standardized risk ratio compared with non-HRT users 0.42 (confidence interval 0.18-0.83)]. HRT use was not associated with greater weight gain than that occurring in other members of the cohort. The baseline and follow-up bone densities in the non-HRT users were highly correlated (0.82 < or = r < or = 0.91, P < or = 0.0001) and baseline bone density accounted for the majority of the variance in the 10-year results. Multivariate analyses showed that the independent correlates of rate of change of bone density were weight and fat mass (both baseline values and changes during follow-up), time after menopause, sex hormone concentrations, urinary calcium loss, PTH levels and haemoglobin concentration (which may reflect nutrition and health). CONCLUSIONS: Bone density is highly predictable over an extended period of time in normal postmenopausal women. Maintenance of body weight and good health reduce bone loss. HRT is effective for treating osteoporosis, with improvement in bone density and reduction in vertebral fractures. Good compliance with HRT long-term is achievable. These findings are relevant to deciding the frequency of bone density measurement, and in advising women regarding prevention and treatment of postmenopausal bone loss.

BACKGROUND: It is still difficult to differentiate pituitary adenoma remnants from postradiotherapy fibrosis by computed tomography (CT) or magnetic resonance imaging (MRI), especially in patients with clinically nonfunctioning pituitary adenomas (NFA), lacking circulating markers to follow disease progression or cure. OBJECTIVE: We investigated the usefulness of scintigraphy with technetium-99m pentavalent dimercaptosuccinic acid [(99m)Tc(V)DMSA], shown previously to detect most pituitary GH- and PRL-secreting adenomas and NFA, with tumour-to-background ratios (T/B) as high as 25-fold. PATIENTS: Eighteen patients with NFA (study group), 10 patients with GH- and three patients with PRL-secreting adenomas (control group), all of whom had undergone previous surgery. DESIGN: The study was an open longitudinal design. Pituitary CT/MRI and (99m)Tc(V)DMSA scintigraphy was performed before and 1, 3 and 5 years after conventional radiotherapy. Tumour size was measured as maximal diameter of the residual lesion, while uptake of (99m)Tc(V)DMSA was measured as a T/B ratio. RESULTS: At study entry, pituitary (99m)Tc(V)DMSA uptake was found in 13 NFA (72.2%), seven GH-secreting (70%) and all PRL-secreting adenomas; remnant tumour was documented by CT/MRI in all 31 patients. Maximal remnant diameter was significantly higher in patients with positive (13.3 +/- 0.9 mm) than in those with negative scintigraphy (7.0 +/- 0.3 mm, P < 0.001). During the 5-year follow-up postradiotherapy, a significant decrease in (99m)Tc(V)DMSA uptake (9.7 +/- 0.8 vs. 3.2 +/- 0.5, P < 0.0001) occurred in all but three patients. Two NFA patients died of tumour invasion 19 and 36 months after radiotherapy and one acromegalic patient had no change in his hormone levels. In the eight negative patients (five NFA and three GH), scintigraphy remained negative throughout follow-up. A remarkable shrinkage of the remnant tumour was observed in both the patients with negative (from 7.0 +/- 0.3 to 1.9 +/- 0.6 mm, P < 0.001) and in those with positive scintigraphy (from 13.3 +/- 0.9 to 7.3 +/- 0.6 mm, P < 0.001). At the end of the study, CT/MRI showed evident remnant tumour in 13 of 16 NFA (81.2%), nine GH-secreting (90%) and all three prolactinomas (100%), while the scintigraphy was negative (T/B < 1) or faintly positive (T/B 1-2) in eight of 16 NFA (50%), five GH-secreting (50%) and one prolactinoma (33.3%). CONCLUSIONS: Functional imaging of pituitary remnant adenomas (> 10 mm in size) by (99m)Tc(V)DMSA depicts viable pituitary adenoma remnants. This approach may be of clinical value in patients with clinically nonfunctioning adenomas to monitor the effects of radiotherapy.

What is the role of the insulin-like growth factor system in the pathophysiology of cancer cachexia, and how is it regulated?

OBJECTIVE AND BACKGROUND: The cancer cachexia syndrome is characterized by anorexia, weight loss with muscle wasting and increased energy expenditure. It is associated with increased morbidity and mortality, but its aetiology is poorly understood and no effective therapeutic intervention is available. It may result from an imbalance between the activity or effect of anabolic and catabolic hormones, mediated by the inflammatory cytokines. IGF-I is a potent anabolic agent, with therapeutic potential. Our objective was to investigate the role and regulation of the IGF system in cancer cachexia. DESIGN AND PATIENTS: We set up a prospective study of 30 patients with newly diagnosed unresectable non-small cell lung cancer, together with a cross-sectional comparison group of healthy volunteers. MEASUREMENTS: We examined the relationship between aspects of the IGF system, including IGFBP-3 proteolysis (using Western ligand and immunoblotting and an in vitro IGFBP-3 protease assay); the inflammatory cytokines and their soluble receptors; and food intake and nutritional status (including biochemical and anthropometric assessments). RESULTS: Although we did not observe a marked reduction in food intake in the cancer patients, the majority lost weight and functionally important lean body mass. We observed GH resistance in the cancer patients, and intermittent proteolysis of IGFBP-3, which correlated with the circulating interleukin-6 (IL-6) concentration. The pattern of IGFBP-3 proteolysis was unusual, with a prominent 17-kDa fragment. Less IGFBP-3 proteolysis was associated with more weight loss, suggesting that this could be a protective counter-regulatory mechanism, increasing IGF-I bioavailability to the tissues. CONCLUSIONS: Cancer cachexia in humans is a complex condition. Patients tend to be GH resistant. The significance of the intermittent increases in IGFBP-3 proteolysis, which may be regulated by IL-6, remains uncertain. A better understanding of the pathophysiology should enable the development of novel therapeutic approaches.

Prescription drugs, surgical hair transplantation, topical application of various oils or creams... Also prayer and wishing...
Hair Million is an alternative approach to hair loss problems.
Anecdotes and personal experiences testify that it works. Hair Million shows positive results and improvement for age-related
hair thinning and hair loss for a large fraction of people who take it.
How does it work? Good question. The molecular biological or clinical mechanisms of action as to how Hair Million exactly works
to help stop hair loss, and promote hair growth is completely unknown.
The only evidences for the effecacy of Hair Million on hair growth are only anedotal and based on personal experiences.
There has been no clinical trials or placebo controlled statistical analysis on the efficacy of Hair Million on hair loss and hair growth.
That's enough for many people. Also, there are two merits in the hair restoration herbal formula:
Firstly, HairMillion is comparatively inexpensive, and secondly, it is made only of herbs
that are known to be safe when consumed in regular quantities. Herbs in Hair Million are also known for cardiotonic effects, meaning
that the herbs will make your heart stronger.
