Faecal fat content in healthy adults by the ‘acid steatocrit method’

Malabsorption syndromes causing steatorrhoea are quite common in India. Estimation of faecal fat is an important non-invasive investigation, which provides vital information regarding the occurrence of malabsorption. The aim of this study was to estimate the fat excretion per day in stools of apparently healthy adults on an unrestricted diet in random spot stool samples using the Acid Steatocrit Method, which provides an alternate, simpler and yet reliable method of stool fat estimation. Several studies have proved the correlation of the acid steatocrit method with the conventional methods. In India, however, there has been no published data regarding the normal levels of fat in the stools, by the acid steatocrit method. We follow the normal range values, as set by the United States and the European countries, not having a range for the Indian population. Hence, we took up a preliminary study, to estimate stool fat in a section of normal and healthy Indian population. The result obtained after screening 600 healthy and normal adults, showed the mean of stool fat to be 8.72 gms/24 hours, which is much higher than that, defined by Western literature (7 gms/24 hours). This can be accounted for, by the cultural and ethnic variations in dietary and food habits. Further studies are required in the same direction, involving larger population groups, and in different malabsorptive conditions.     

Cord Blood Insulin Levels: It’s Correlation with Gender,Birth Weight and Placental Weight in Term Newborns

The cause of more insulin resistance in female than males are still unknown. To know the cause from early life, normal values of relevant parameters are required. So, aim of this study was to determine the reference levels of glucose and insulin in cord blood of term newborns and to examine their effects on gender, placental and birth weight of term newborns. In cross sectional study 60 consecutive term newborns were included from constituent hospitals. Placental and birth weights were measured and cord blood was collected for estimation of serum insulin and plasma glucose. Plasma glucose estimation was done by auto analyzer (GOD–POD method) and serum insulin analysis was done using Insulin ELISA Kit. After analysis, mean ± 2SD used for estimating cord blood insulin and glucose levels, which were 10.1 ± 7.8 μIU/mL and 67.8 ± 33.8 mg/dL respectively. Correlation of insulin with both birth weight and placental weight were r = 0.359 and 0.41 respectively; p < 0.001. Interestingly we found higher insulin levels in females as compared to male newborns in spite of having lower birth weight in them. In conclusion this study reported the levels of insulin and glucose in cord blood of term newborns. Incidentally, this is the first study as per our knowledge to report significant correlation between cord blood insulin, glucose with birth weight, placental weight and gender in south India. Female newborns had higher insulin levels than males, despite lesser birth weight can be attributed to intrinsic insulin resistance in them.     

Software vulnerability due to practical drift

The proliferation of information and communication technologies (ICTs) into all aspects of life poses unique ethical challenges as our modern societies become increasingly dependent on the flawless operation of these technologies. As we increasingly entrust our privacy, our well-being and our lives to an ever greater number of computers we need to look more closely at the risks and ethical implications of these developments. By emphasising the vulnerability of software and the practice of professional software developers, we want to make clear the ethical aspects of producing potentially flawed software. This paper outlines some of the vulnerabilities associated with software systems and identifies a number of social and organisational factors affecting software developers and contributing to these vulnerabilities. Scott A. Snook’s theory of practical drift is used as the basis for our analysis. We show that this theory, originally developed to explain the failure of a military organisation, can be used to understand how professional software developers “drift away” from procedures and processes designed to ensure quality and prevent software vulnerability. Based on interviews with software developers in two Norwegian companies we identify two areas where social factors compel software developers to drift away from a global set of rules constituting software development processes and methods. Issues of pleasure and control and difference in mental models contribute to an uncoupling from established practices designed to guarantee the reliability of software and thus diminish its vulnerability.     

Effect of thiazide drug compound on the testicular protein and cholesterol contents of albino rat

In this study the effect of thiazide diuretic compound on the protein and cholesterol contents in the testes of albino rats as the experimental model. The drug thiazide was administered orally daily for 10,20 and 30 days at the dose of 100mg/kg body weight. Total protein decrease in the testes of rats were evidenced may be due to the side effects of thiazide drug compound which is linked with the hyponatremia and protein metabolism. An elevated level of cholesterol contents observed in thiazide treated rats also revealed that the side effect of drug compound thiazide and also may be due to the stimulation of catecholamine which is stimulated therefore, the biochemical estimation such as protein and cholesterol in the testes after the thiazide treatment determined the effectiveness of diuretic drug compound would provide clinical evidences of their side effects.
