84 cases observed were divided into 4 types according to principles of diagnosis and treatment based on an overall analysis of symptoms and signs, namely: Yang-deficiency of the Spleen and Kidney (62 cases, 73.8%), Yin-deficiency leads to internal heat (6 cases), deficiency of both the Heart and the Spleen (7 cases), and prostration of Qi after loss of blood (9 cases). The patients were treated with the method of warming and tonifying the Spleen and Kidney by using Er-Xian decoction of warming the Kidney. The three other types were also treated with the method after being relieved with the methods of tonifying the Heart and the Spleen, of nourishing Yin to relieve internal heat and cooling blood, and of strengthening Yang to stop chronic hemorrhage respectively so that function of the blood and Qi would promote each other and be improved...

Mecamylamine, an antagonist to nicotine, does not compete at the nicotinic recognition site, but is believed to block the ion channel of the nicotinic receptor. The present study demonstrates specific, saturable [3H]mecamylamine binding in rat brain membranes. [3H]Mecamylamine binding was destroyed by heating at 100 degrees and trypsin. Scatchard analysis revealed the presence of two sites with Kd values of 9.6 x 10(-8) and 1.1 x 10(-6) M and Bmax values of 7 x 10(-12) and 3 x 10(-11) mol/mg protein respectively...

One study was conducted utilizing 192 male broilers, at 4 to 7 wk posthatching, to evaluate a narasin-nicarbazin drug combination (Maxiban) for effects on bird growth rate, feed efficiency, and survivability during cycling ambient temperature (24 to 35 C) distress. Maxiban did not impact (P greater than .1) live weight gain, but reduced (P less than .05) gain:feed ratio (unadjusted for mortality), from .29 for controls to .21 as bird survivability declined (P less than .05) from 87.5 to 69.8%. Adjusting feed efficiency by adding the gain of birds dying of heat prostration to that for birds surviving the experiment resulted in feed efficiency for Maxiban-supplemented birds being similar (P = ...

The possibility that prolonged heat exposure resulting in a failure of central thermoregulatory mechanism may induce cellular damage in brain was examined in young rats. Children exposed to Indian summer heat can develop sudden pathophysiological symptoms. Subjection of young animals to similar acute systemic heat exposure at 38 degrees C (relative humidity, 46%) for 4 h resulted in a profound hyperthermia, and behavioral stress symptoms e.g. salivation and prostration. Subsequent morphological examination of the brain tissue revealed profound cellular changes...

The possibility that serotonin may play a role in heat adaptation was examined in a rat model of heat stress (HS). Subjection of animals to acute 4 h HS (but not to 1 h and 2 h duration) in a biological oxygen demand (BOD) incubator (relative humidity 50-55%, wind velocity 20-25 cm/s) resulted in profound hyperthermia (41.68 +/- 0.25 degrees C) associated with behavioural salivation and prostration. This experimental condition simulates the out door environmental conditions of Varanasi, India during the month of June...

The interaction of nutritional status on the tolerance of young chicks to acute heat stress (HS) was investigated. The results of experiment 1 demonstrated that fasting for 24, 48 or 72 hours progressively increased survival time (ST) of chicks exposed to HS. When compared to that of non-fasted (NF) chicks ST more than doubled for 48 and 72 hour fasted chicks. During HS plasma glucose increased in fasted chicks but decreased in NF chicks. Conversely, plasma free fatty acids decreased in fasted chicks and increased in NF chicks...

The records of all children in the Tucson area diagnosed as having cystic fibrosis (CF) before the age of 12 months were reviewed to ascertain the prevalence of metabolic alkalosis as a major presenting manifestation of CF. Five of eleven infants (46%) in whom CF had been diagnosed between 1 and 12 months of age initially were seen with hypokalemia, hypochloremia, and metabolic alkalosis unassociated with marked dehydration, hyperpyrexia, or major pulmonary and/or gastrointestinal symptoms. Two infants had repeated episodes of metabolic alkalosis; for one of these infants, both episodes of metabolic alkalosis occurred before the diagnosis of CF...

Many previous studies have demonstrated effects of gonadal steroids on adrenal weight in the rat. Most of these effects are indirect, depending upon alterations in the pituitary-adrenal axis for their expression. In this study we have attempted to examine the direct effects of gonadal steroids on adrenal weight in the rat. This was done using hypophysectomized, castrated male rats receiving ACTH replacement, a model which excludes pituitary-adrenal feedback effects. Estradiol-treated rats did not differ from controls, whereas testosterone-treated rats exhibited a small but statistically significant decrease in adrenal weight...
