Monitoring the pathophysiological correlates of postmenopausal hot flushes

Clinical assessment of the severity and frequency of post-menopausal hot flushes can be made objectively by measuring the associated changes in skin conductance and skin and core temperature. Such measurements provide a more reliable index of the response to therapy than does subjective reporting which has been employed in the past. The design and use of a working analyzer is presented that is sufficiently simple, rugged, safe and portable to be used under normal clinical conditions to provide a permanent record of the attacks.     

Intra-oral temperatures during function

There has been limited published research assessing the range of oral temperature that the dental hard and soft tissues are exposed to. The temperatures that tooth structure and dental restorations encounter affect the performance of dental materials within the oral environment. This study therefore assessed the range of temperatures that a selected group could tolerate when drinking and also assessed the range of temperatures encountered in various intra-oral sites. These temperature fluctuations are for very brief periods of time but have a wide and varied range. Miniature dataloggers allowed for accurate measurements and recording of temperature from selected sites. The range of temperature recorded amongst the individuals tested shows the protection afforded to the dental hard tissues by the soft tissues of the oral cavity. The maximum and minimum mouth temperatures recorded show that hot fluids can raise the intra-oral temperature of the front teeth to around 70 degrees C and the consumption of iced drinks lowers the same teeth to around 0 degrees C. The range of temperature of hot fluids that can be tolerated by a selected group vary, but this does not seem to be the case for cold fluids. The thermistor beads mounted on the buccal surface of the lower front teeth and the palatal of the upper front teeth are exposed to the greatest temperature fluctuations during drinking fluids from a cup. The importance of these temperatures recorded in terms of dental materials testing and the role of material conductivity warrants further investigation.     

Histological investigations on the effects of feeding a diet containing red hot pepper on the reproductive organs of the chicken

In the present study the growth and reproductive organ differences in chickens fed a diet containing 1% red hot pepper (10 g/kg diet) from the first day of age were investigated. In birds fed with the experimental diet it was observed that the abdominal fat content decreased. During the experiment the increase in weight gain in the treated group in the first 4 months was reversed in favour of the control group in month 5. Follicular development in the treated group was faster and laying started 11 days before the control group, and the epithelial and muscular development of the oviduct was always greater than that of the control group.The results indicated that red hot pepper consumed in lower concentrations during the development period in the chickens caused faster development of the reproductive system organs. Laying started 11 days earlier in chicks fed with the red hot pepper added diet, an important economic aspect for egg producers, but which may have implications for other animals. A decrease in abdominal fat content and disorders of lipid metabolism are still under investigation.

Postmenopausal women with vasomotor symptoms have increased urinary excretion of calcitonin gene-related peptide

Objectives: To establish whether 24 h urinary excretion of the potent vasodilator calcitonin gene-related peptide (CGRP) was higher in postmenopausal women with vasomotor symptoms compared to the level in women without symptoms. We also wanted to establish whether urinary excretion of CGRP changed during the menstrual cycle in women of fertile age. Material and methods: Thirteen postmenopausal women with and 13 women without vasomotor symptoms were included. Urine was collected over 24 h and CGRP excretion was measured utilizing radio-immuno assay technique. Twenty-four hour CGRP excretion was also measured in ten fertile women with regular cycles in early follicular, preovulatory and midluteal phase. Results: Twenty-four hour urinary excretion of CGRP was significantly higher in women with vasomotor symptoms compared to non-flushing women (median 7.16 vs 5.15 pmol/24h; P=0.028). CGRP concentrations were stable throughout the ovulatory cycles. Conclusion: The 24 h urinary excretion of CGRP is higher in women with vasomotor symptoms than in women without these symptoms. CGRP may be the mediator of vasodilator signals originating from the thermoregulatory center.
