Abstract
The relationship between socio-demographic and behaviour variables and body mass index (BMI: weight/height2) adjusted for age were studied in a population with high-normal blood pressure who participated in the Hypertension Prevention Trial. The BMI of the participants ranged from 19.1 to 35.1 kg/m2 in men and from 16.0 to 35.1 kg/m2 in women. The prevalence of obesity (BMI greater than or equal to 25.0 kg/m2) was 77 per cent in men and 61 per cent in women, with prevalence of severe obesity (BMI greater than or equal to 30.0 kg/m2) being 23 per cent and 19 per cent respectively. Stepwise regression was carried out to identify the most important correlates of BMI. In men, they were family income (+), occupation (-), leisure time exercise frequency (-), number of meals eaten out (-), alcohol intake (-), smoking (-), caffeinated drink intake (+), and meal planner. Men who planned meals with their partners had a higher BMI than men who planned their own meals or had someone else plan their meals. Correlates of little importance were marital status, race, education, number of members in household, energy intake, percentage of total calories from fat, occupation activity level, and vitamin/mineral supplement intake. In women the most important correlates of BMI were alcohol intake (-), caffeinated drink intake (+), and race. Black women had a higher mean BMI than white women. The important socio-demographic and behaviour variables in both men and women accounted for about 20 per cent of the variance in BMI which leaves about 80 per cent of the variation unexplained. This indicates the presence of other factor(s) which may be determining body weight.

Abstract
Xanthogranulomatous pyelonephritis is the replacement of renal parenchyma by large lipid-filled macrophages clinically associated with an enlarged, nonfunctioning kidney containing a calculus in the diffuse form or tissue destruction in one pole of a duplicated kidney associated with a calculus in the focal form. We report a case where a focal mass in a functioning kidney with no evidence of calculus, duplication, or fat density simulated a primary renal tumor.

Abstract
Variations in the mucin secretion pattern in the mucosal lining of the colon and rectum have been studied. Mucins have been differentiated histochemically as neutral mucins, sialomucins and sulphomucins, using alcian blue/PAS and HID/alcian blue techniques. In the normal colonic mucosa, the goblet cells secrete predominantly sulphomucins with small amounts of sialomucins. Twenty one cases with benign lesions showed varying patterns of mucin secretion. In the 35 cases with adenocarcinoma studied, the transitional mucosa adjacent to the lesion showed a reversal of mucin secretion pattern, with an increase in sialomucins and a marked decrease in sulphomucins, suggesting a reaction to neoplasia.

Abstract
Histochemically differentiated mucins have been studied in the mucosal lining of the esophagus and the stomach. Acid mucin was differentiated from neutral mucin by the alcian blue/PAS technique and sulphomucin by the high iron diamine/alcian blue technique. Neutral mucin secreted normally by the stomach mucosa was replaced by acid mucin in 17 of the 19 mucin secreting adenocarcinomas involving the lower third of the esophagus, and in 24 of the 28 mucin secreting gastric adenocarcinomas studied. The intestinal metaplasia (IM) seen in the gastric mucosa associated with adenocarcinoma, chronic gastric ulcer and chronic gastritis was classified according to the type of mucin secreted by the goblet cells. IM secreting sulphomucins was seen to be associated with gastric adenocarcinoma.

Abstract
A patient with acute inflammatory demyelinating polyradiculoneuropathy (AIDP, Guillain-Barré syndrome) whose presenting complaints were related to autonomic dysfunction in the form of parasympathetic and sympathetic overactivity is reported. Parasympathetic overactivity was severe enough to cause complete atrioventricular block (atropine-responsive) and Stoke-Adams attacks, for which a demand pacemaker was required. Limb weakness was apparent 48 hours later. To our knowledge no such presentation of AIDP has been previously recorded.

Abstract
Lectin binding of goblet cell mucin in human colonic mucosa was studied in patients with irritable bowel syndrome, colorectal malignancy and ulcerative colitis using plant lectins, Dolichos biflorus agglutinin (DBA) and peanut agglutinin (PNA). Normal colonic mucosa demonstrated a strong binding with DBA (100%) but did not bind to PNA at all. Colonic carcinomas showed strong PNA binding (7 of 15 biopsies) while DBA binding was absent in 14 of 15 biopsies. The transitional mucosa showed reduced or absent DBA binding in 6 and positive PNA binding in 2 of 15 biopsies. During the active phase of ulcerative colitis, there was a loss of DBA binding in 10 of 15 biopsies, which was restored during remission in all. One biopsy with severe dysplasia showed PNA binding. It is concluded that normal colorectal mucosa binds DBA strongly but not PNA. Malignant tissue and transitional mucosa reveal PNA binding often, with decreased DBA binding. In ulcerative colitis DBA binding decreases during phases of activity.

Abstract
Components of daily metabolic rate (thermogenesis, BMR and net exercise) were compared between 16 women predisposed to obesity (post-obese) and 16 naturally lean controls of matching age, weight and height, at three levels of activity, in a whole-body respirometer. At all levels of activity, the mean metabolic rate of the post-obese was 15 per cent lower than that of the lean controls. Expenditure on net exercise showed the same relationship, but BMR was only 10 per cent lower, while thermogenesis was 50 per cent lower. The latter was partly due to the smaller food intake of the post-obese and also to a lower thermogenic response. In absolute terms BMR accounted for less than half of the difference in total energy expenditure between the post-obese and the lean (45 per cent). Thermogenesis accounted for approximately 40 per cent of the difference, and 15 per cent after adjusting for the different energy intakes. Significantly more post-obese subjects had a family history of obesity (88 per cent) than lean subjects (38 per cent). Within the post-obese and lean groups there was a consistent trend at each level of activity for those with a family history to have lower metabolic rates, indicating that family history of obesity has an influence on energy expenditure over and above personal history of obesity.

Abstract
To determine the timing of the development of the various palmar and digital creases, we examined the hands of 100 human fetuses obtained after therapeutic abortion. The fetuses ranged in age from 7 to 19 fetal weeks, with age being established by menstrual period dates and ultrasound examination before termination. Our observations show that palmar and digital creases develop between 8 and 13 fetal weeks. Digital creases are well defined by 10 weeks; palmar creases are consistently seen by 13 weeks of gestation. The volar pads are present from 8 to 14 fetal weeks. A hand malformation or specific insult that occurs before the time of crease development and that alters the form or function of the fetal hand can cause secondary alterations increase patterns of the hand.

Abstract
The effect of aerobic exercise (cycling on bicycle ergometer for four 10-min periods/60-80 per cent max VO2) on energy expenditure following the activity was investigated in 16 post-obese and 16 lean control women over 24 h and shorter periods. In addition, net energy expenditure during aerobic exercise was compared to that during prolonged mild activity (stepping for four 30-min periods at 12 steps/min). The measurements were made in a room respirometer. Aerobic exercise did not significantly stimulate the 24-h resting metabolic rate of either the post-obese (3 per cent, 50 kcal) or lean controls (2 per cent, 30 kcal), nor was there any significant stimulation over shorter periods: during waking hours RMR was non-significantly increased by 5 per cent in both the post-obese and lean controls. Sleeping expenditure remained the same in the post-obese and was decreased by 2 per cent in the lean controls. All subjects found the aerobic exercise to be quite uncomfortable, yet in both groups the net cost was smaller than that of prolonged mild exercise which was found to be acceptable (post-obese: aerobic 180 kcal, mild 250 kcal; lean controls: 220 kcal, 290 kcal). It is suggested that prolonged mild activity (eg, as in walking frequently) is more appropriate in increasing energy expenditure as a means of preventing or controlling obesity. Total expenditure at each level of activity is also expressed as multiples of BMR calculated from FAO/WHO/UNU (1985) prediction equations and from measured sleep values. The results show that the equations overestimated BMR in the post-obese.

Abstract
Daily metabolic rates of 16 post-obese women and 16 matched, lean controls were measured at three different levels of activity in a room respirometer. Both groups had similar height, weight, age, and other anthropometric indices. Results show that the post-obese have metabolic rates approximately 15% lower than their controls at any level of activity. They also eat less. Slimmed-down, obese women have a normal body composition. For both groups, aerobic exercise did not have a prolonged stimulatory effect on metabolic rate after the exercise had finished. Mild exercise was more effective than aerobic exercise in increasing daily metabolic rate because it could be comfortably sustained for a longer time. Implications of these findings are discussed in relation to the etiology and treatment of obesity.

Abstract
A child in whom a phenobarbital hypersensitivity drug reaction developed which consisted of fever, a pruritic desquamating erythrodermic rash, alopecia, icterus, protein-losing enteropathy, myositis, and nephritis, is described. Laboratory studies demonstrated eosinophilia, elevated serum IgE, and elevated T suppressor/cytotoxic cells in the peripheral blood. Findings from biopsy specimens of skin and jejunum suggested a cell-mediated pathogenesis, and lymphoproliferative studies of the patient's mononuclear cells revealed a positive response to phenobarbital. The clinical findings and laboratory studies suggested an autoimmune cell-mediated hypersensitivity reaction triggered by phenobarbital.

Abstract
Premedication with nalbuphine and morphine delayed gastric emptying in the period after operation, but oral diazepam did not. All three drugs delayed co-ordinated intestinal motility, although nalbuphine did so for less than half as long as morphine. This property of nalbuphine, if confirmed, could make it a valuable analgesic drug in the period after operation.

Abstract
A case is presented of callosal syndrome following cerebral hemorrhage and amphetamine abuse in a 26-year-old right-handed man. There were few hemispheric findings but a full callosal syndrome including left apraxia to verbal commands, left tactile anomia, left agraphia, right constructional apraxia, failure of blindfolded side-to-side hand replication and form-board testing showing loss of interhemispheric transmission including intermanual interference. The "draw-a-clock" test showed left inattention when drawn with the right hand but not the left, and perseveration was noted for spatial tasks done with the right hand and symbolic tasks done with the left. The patient recovered functionally almost completely but testing demonstrated continued loss of interhemispheric transmission. The case is considered of most interest for its potential in explaining phenomena observed in severe unilateral hemispheric lesions. Our findings suggest that perseveration is not a dysfunction of the damaged portion of the brain, but a phenomenon associated with intact brain attempting unfamiliar tasks. The persistence of left hemi-inattention is attributed to the inability of the left hemisphere to utilize spatial information to compensate for the phenomenon of inattention. Left-sided dyskinesia following left hemisphere lesions was attributed to the lack of symbolic information necessary to perform some movements. Dysprosody was attributed to lack of tonal information to the left hemisphere. Recovery of function following severe unilateral lesions may be largely due to compensatory learning by the intact hemisphere and assertion of ipsilateral control. As our patient originally assumed an inverted left-handed writing posture, we assume the posture is controlled by the right hemisphere.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Liposomes have a pronounced tendency to localize in the reticuloendothelial (RE) system, a major host defense system. We have examined, in mice, the effect of chronic i.v. administration of low to moderate liposome doses on drug metabolism, phagocytic index and spleen and liver size. Little effect on the rate of pentobarbital metabolism was noted, except when mice received 80 mg/kg of sphingomyelin-containing liposomes in a series of 10 injections over 3.5 weeks. Impairment of RE phagocytic function was found to be related to liposome size and composition, size and frequency of liposome dose and the presence of lipid peroxides. The effects on tissue distribution of liposome-entrapped [14C]sucrose was also determined in mice receiving chronic liposome injections. In RE blockaded mice there was a consistent trend in favor of decreased liver uptake and increased spleen uptake. No significant uptake of liposome contents was seen in non-RE tissues even in mice with severe RE blockade, indicating that the induction of RE blockade by predosing with empty liposomes may not be a successful strategy for increasing liposome uptake to non-RE tissues. Liver to spleen ratios of [14C]sucrose appeared to be a sensitive method for quantitating RE blockade. Sphingomyelin-containing liposomes produced the greatest RE blockade, distearoylphosphatidylcholine-cholesterol liposomes were intermediate and egg phosphatidylcholine-cholesterol liposomes produced the least impairment in RE function. Liposomes which contained 1% vitamin E as an antioxidant had slightly less effect on RE function than liposomes not containing vitamin E.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Increased plasma levels of beta-thromboglobulin (beta TG) and fibrinopeptide A (FPA), markers of platelet release and thrombin generation respectively, were measured in normal women, women taking oral contraceptives, normal pregnancy and pregnant women with hypertension or pre-eclampsia. No significant increases in beta TG or FPA were found in women taking oral contraceptives. Significantly increased concentrations of beta TG, but not FPA, were found in normal pregnant women in the second and third trimester of pregnancy when compared with non-pregnant age-matched controls. In eleven women with pregnancy hypertension and thirteen women with pre-eclampsia significantly elevated levels of both beta TG and FPA were found when compared with age, parity and gestation-matched pregnant controls. Although the mean value for both beta TG and FPA in the group with pre-eclampsia was higher than the group with pregnancy hypertension, the difference was not statistically significant. These findings provide additional evidence that pre-eclampsia and pregnancy hypertension are associated with activation of the coagulation system and the platelet release reaction.

Abstract
Six healthy castrated male goats were each given 1.0, 1.25 or 1.5 ml of carbon tetrachloride per 10 kg BW by stomach tube (2 animals at each dose level). Definite signs of dose dependant liver damage were seen, starting about 4 hours after administration of the drug. The clinico-chemical changes included increased total and conjugated plasma bilirubin, decreased blood clotting activity, and increased activities of P-ASAT and P-GT. Further experiments are needed in animals afflicted with liverflukes to establish the lowest possible anthelmintic dose of carbon tetrachloride.
