Retrieval of foreign body from upper GI tract by flexible fibreoptic endoscope--an experience.
Forty foreign bodies (29 located in oesophagus and 11 located in the stomach) were removed by means of a flexible fibreoptic endoscope over a period of two years. The foreign bodies consisted of coins, a pin, a needle, a big button, a key ring, a fish bone, a denture, some fruit seeds, a meat bolus, a lock, a golden chain, a diamond nose ring, an ear top and a nasal catheter. Age of the patients ranged from four months to eighty years. Anaesthesia was required in 5 paediatric patients. Thus this method was found to be a safe, rewarding and non-operative one.

A radiotherapeutic clinical trial of twice per week vs. five times per week in oral cancer.
135 cases of oral cancer have been treated by two fractions per week, and the results are compared with 115 approximately identical cases treated by conventional five days a week schedule with other parameters being identical. Radical irradiation was done by 6000 and 6500 rd in 6--6 1/2 weeks (NSD 1800--1900 ret) and palliative dose was 4500 R/4 weeks (NSD 1532 ret). Tumour regression was found markedly superior by conventional regime in radically irradiated cases but much less superior for palliative treatment. Acute and late reaction as well as tumour control at 1 year was better with daily treatment, more so in cases treated for radical cure, while in palliative treatment, the superiority of daily regime was less marked. Our study provides evidence that only for palliation in advanced cases, radiation therapy by 2 fractions a week can be alternatively used.

Reflex responses of abdominal vascular capacitance from aortic baroreceptors in dogs.
The vascularly isolated abdominal circulation of chloralose-anesthetized dogs was perfused at constant flow through the aorta and drained at constant pressure from the inferior vena cava. Changes in resistance were calculated from changes in perfusion pressure and changes in capacitance were calculated by integrating changes in venous outflow. While carotid sinus pressure was constant, a decrease in pressure in the vascularly isolated aortic arch, over the whole range of baroreceptor sensitivity, decreased abdominal vascular capacitance by 2.9 ml-kg-1 (mean, SE +/- 0.42) and increased the abdominal vascular resistance by 35 +/- 7.1%. Decreases in pressure in the vascularly isolated carotid sinuses, while aortic pressure was constant, decreased capacitance by 5.0 +/- 0.62 ml-kg-1 and increased resistance by 72 +/- 15.9%. Responses of capacitance and resistance to changes in aortic pressure were greatest when carotid pressure was held near threshold levels and least when it was held at levels that would maximally excite carotid baroreceptors. The responses to changes in aortic pressure were abolished when the venous nerves were cooled or the splanchnic nerves were cut.

Non-random distribution of various sizes of human Y chromosomes in different ethnic groups.
One hundred and ninety normal males from three ethnically different populations (Caucasians, American blacks and East Indians) were selected to study the frequency distribution of length of the Y chromosome, fluorescent (f) and non-fluorescent (nf) segments as a function of Y/F, f/F and nf/F indices. The QFQ techniques was performed to identify the f and nf segments. The frequency distribution of the total length of Y chromosome was not normally distributed in all three populations (P less than 0.05). Extensive statistical analysis revealed that the non-random distribution of the total length was due to skewness and kurtosis for both the n and nf segments. The clinical implications as well as evolutionary aspects of such variation in ethnic anthropology are discussed.
