Studies on the possible mechanism of the gastric mucosal protection by Calotropis procera — involvement of 5-lipoxygenase pathway

Summary— The role of chloroform fraction of Calotropis procera root extract on different experimental ulcer models in rats was investigated. The extract demonstrated significant anti-ulcer activity against aspirin, indomethacin, ethanol, indomethacin + ethanol, or stress-induced ulcerations. Significant inhibition of gastric secretory volume and total acidity in pylorus ligated rats were observed to occur with the extract. It was also observed that the root extract significantly inhibited arachidonic acid metabolism induced by soyabeian lipoxygenase. The results suggest that the anti-ulcer activity of the extract might be attributable to the inhibition of 5-lipoxygenase (5-LO).     

Carcinoma of the breast: detection with MR imaging versus xeromammography

Detectability of breast cancer with magnetic resonance (MR) imaging versus xeromammography was quantitatively compared. MR images were obtained of breasts of 120 women who underwent xeromammography. T1 values were determined for masses larger than 2 cm. Cancer was histologically confirmed in 39 breasts and was considered excluded from 81 due to results of biopsy, cyst aspiration, or sonography or absence of change in xeromammographic findings over time. Images were blindly interpreted by three observers, and results were expressed as receiver operating characteristic curves. Detectability of breast cancer was substantially better with xeromammography than with MR imaging for all observers (P less than .03, 10(-6), and .001). On MR images, spiculation of a mass, distorted architecture, skin thickening, and nipple or skin retraction were specific but relatively insensitive indicators of cancer. Masses with smooth, distinct margins and signal intensity greater than that of fat on T2-weighted images were always benign. Other findings and T1 values were not diagnostically useful. The authors conclude that xeromammography is superior to MR imaging in detection of breast cancer.     

Evaluation of Race by Cranial Index of Adult Human Skull in Maharastra Population

Biologists and physical anthropologists attempted to classify human being into races according to phenotypic variations. The latter are based either on one or two phenotypic characters therefore the outcome is unable to givq clear distinction among different races. Cranial index seems to be an important,tool, which may be used to identify the races in different geographical regions. 75 dried skulls collected from different part of Maharashtra were measured to determine the cranial index. Skulls were classified by the method of Montagu (1960)2 Average maximum cranial length and breadth were found to be 17.11 cm and 12.98 cm respectively and maximum & minimum cranial lengths were observed to be 18.50 and 16.60 cm and cranial breadths were noted to be 14.50 and 12.10 cm respectively. Average cranial index (mean ± SD) was 75.49 ± 3.95. In our study most of the skulls were grouped under the Mesocranial (46.66%) and Dolichocranial (42.66%) categorises when based on Montagu and Dolichocranial categorises when 56% based Comas'. As per the conclusion Maharashtrian population belongs to Indo-Dravidian race.     

Oral and general health-related quality of life among young patients with haemophilia

Summary.  The clinical diagnosis of dental diseases may indicate their cause and prognosis, however it gives little information about resulting levels of impairment from the patients' perspective. In this study, we aimed to investigate oral and general health-related quality of life (OHRQoL-HRQoL) in patients with haemophilia; and to test whether haemophiliacs would have worse or better OHRQoL compared with the general population. Data were collected from haemophiliacs (age range 14–35; mean 23 ± 6.58, n  = 71) and age/sex-matched controls (age range 14–35; mean 21.00 ± 6.45, n  = 60) through face-to-face interviews including nine questions and using oral health impact profile (OHIP)-14, oral health-related quality of life-UK (OHQoL-UK), short-form general measure of health (SF)-36 to measure self-rating oral health status, perceived dental treatment needs, tooth brushing frequencies, OHRQoL-HRQoL. In the field of self-rating oral health status, perceived dental treatment needs, tooth brushing frequencies and OHIP, OHQoL-UK, SF-36 scores – except the subscales including vitality, role emotional and mental health – the control group is in better conditions compared with the haemophilia group. At the same time, both the two groups are in good conditions in dental attendance, vitality, role emotional and mental health. Life quality is related with the perceived discrepancy between the reality of what a person has and the concept of what that person wants, needs or expects. In order to eliminate the dilemma in the field of health, we should facilitate the haemophiliacs' lives by serving the health care in a multidisciplinary view.
