Effects of ethanolic extract of Iris germanica on lipid profile of rats fed on a high-fat diet.

Ethanolic extract of Iris germanica rhizomes was investigated for hypolipidemic activity. I. germanica belong to the family Irdaceae and has been used to treat liver and spleen ailments in traditional system of medicine. Two groups of Wistar rats were fed with high-fat diet and ethanolic extract of I. germanica were administered orally in one group of rats, while other received saline for 10 weeks. Complete lipid profiles of experimental animals were determined by assessing serum levels of total lipids, triglycerides, cholesterol, high-density lipoprotein-cholesterol (HDL-C) and low-density lipoprotein-cholesterol. Results indicate that ethanolic extract of I. germanica significantly lowered the lipid components especially, the cholesterol and triglycerides.

Effect of interval between swallows on oesophageal pressures and bolus movement in normal subjects - Studies with combined multichannel intraluminal impedance and oesophageal manometry.

The effect of closely spaced swallows to decrease peristalsis ('deglutitive inhibition') is believed to be due to both central inhibitory impulses and smooth muscle refractoriness. Ten volunteers (three females, age 26-65) were given both four pairs and two series of four swallows at 5-, 10-, 15-s intervals and control swallows at 30-s intervals. Oesophageal function was assessed using combined multichannel intraluminal impedance and oesophageal manometry (MII-OM). Swallows were considered manometrical effective if distal oesophageal pressures >/=30 mmHg. Complete bolus transit was defined as bolus exiting from all three distal impedance segments. During swallowing at 5-s intervals the majority of initial swallows were ineffective with incomplete bolus transit while the last swallow in both series and pairs was manometrically effective with complete bolus transit. During swallowing at 10-15-s intervals the number of manometric ineffective swallows and swallows with incomplete bolus transit progressively increased with the number of swallows. The functional information obtained by MII-OM indicates pooling of liquid in the distal oesophagus that is cleared by the last swallow determined by, previously reported, neural inhibition occurring during swallowing spaced 5 s apart whereas incomplete bolus transit is related to manometrically ineffective swallows resulting from muscle refractoriness occurring during swallowing at 10-15-s intervals.

Spontaneous rupture of liver in a non-pregnant patient: case report.

Spontaneous rupture of the liver during pregnancy associated with preeclampsia is an uncommon and frequently fatal complication. A case of a 61-year-old non-pregnant female is described here who took estrogen replacement for 16 years and presented with spontaneous rupture of the right lobe of the liver with hemoperitoneum. The underlying cause of the rupture was not clear.

Meconium aspiration syndrome: the role of resuscitation and tracheal suction in prevention.

We reviewed our experience of meconium staining of liquor and meconium aspiration syndrome over a 33 month period. The clinical and radiological severity of disease was assessed in comparison with tracheal suction and resuscitation. Sixty (27%) of newborns with meconium stained liquor subsequently developed MAS. No association was found between the thickness of meconium or its presence on tracheal aspiration with subsequent severity of respiratory disease. However, the presence of meconium in the trachea was strongly associated with radiological abnormality. The severity of meconium aspiration syndrome and mortality were also related to the clinical stability of the infants at presentation. Our results indicate that intrauterine aspiration and pulmonary maladaptation may play a significant role in meconium aspiration syndrome rather than resuscitative events at delivery.

Larvicidal activity of actinomycete isolate against Toxocara canis.

A soil isolate of actinomycete, strain S-70, revealing presence of plasmid(s) was placed in the genus Streptomyces according to the wall composition and morphology. The toxicity of S-70 grown on two fermentation media, glucose-asparagine broth (GAB) and malt extract-yeast extract broth (MYE), against infective larvae of Toxocara canis was assessed. The use of mortality test has provided a sensitive and reproducible bioassay. The results suggest high larvicidal activity of the Streptomyces crude products examined being highly potent when using GAB culture medium.

A liver transplant center experience with liver dialysis in the management of patients with fulminant hepatic failure: a preliminary report.

Among extracorporeal liver support devices, liver dialysis is cleared by the U.S. Food and Drug Administration to be used for the management of fulminant hepatic failure (FHF). The outcomes of patients following liver dialysis need to be clearly evaluated. Among the 25 patients with FHF admitted to the Liver ICU between May 2000 and November 2002, 12 underwent liver dialysis, including 6 men and 6 women, of mean age 32 years. The causes of FHF were identified as acetaminophen (n = 10), herbal medications (n = 1) and autoimmune disease (n = 1). At presentation, the mean total bilirubin was 9.35 mg/dL (range, 0 to 1.3), mean ALT 3015 U/L (range, 0 to 48), mean AST 3457 (range, 0 to 42), mean ammonia 98 micromol/L (range, 10 to 60) and mean INR 1.88. A control group including 13 patients (2 men and 11 women), of mean age 27.8 years mean total bilirubin 5.66, mean ALT 3494, mean AST 3528, mean ammonia 113 and mean INR 3, were not treated with liver dialysis, due to the lack of machine availability or physician's choice. The causes of FHF were acute hepatitis B (n = 1), acetaminophen (n = 10) or unknown (n = 2). There was no statistically significant difference in the baseline characteristics of the two groups (P >.05). Among the liver dialysis group, 1 patient died, 2 underwent OLTx, and 9 were discharged home. Among the control group; 4 patients died, 2 underwent OLTx, and 7 were discharged home. Preliminary results seem to support survival benefit among patients who underwent liver dialysis compared to non-liver dialysis; however, further randomized control trials are warranted to verify this observation.

Novel bursting patterns emerging from model inhibitory networks with synaptic depression.

Studies show that short-term synaptic plasticity plays important roles in neural coding and the normal operation of the synapse. Basket cells in the hippocampus demonstrate this plasticity in the form of synaptic depression, and recent in vivo work indicates that basket cell activities contribute significantly to hippocampal output associated with different behavioural states. Thus it is essential to understand the generation and synchronization of patterns produced by basket cell networks with depression. We study two-cell model inhibitory networks with depression and obtain alternating bursting patterns and synchronous activity occurring between bursts. We describe mechanisms for how these patterns emerge by performing several simulations in the plane of different depression time constants, tauD. Such patterns might contribute significantly to various population activities observed in the hippocampus.
