ABSTRACT
La terapia de la tuberculosis con el esquema 2RHZE/4HE comprende la administración durante seis meses de rifampicina, isoniazida, pirazinamida y etambutol, de las cuales las tres primeras son potencialmente hepatotoxicas y excepcionalmente nefrotoxicas. La tuberculosis produce depleción de la concentración de zinc lo que incrementa la susceptibilidad a la cronicidad de la infección. OBJETIVO: evaluar el efecto de la administración conjunta de zinc y la terapia 2RHZE/4HE sobre la función hepática y renal en pacientes con tuberculosis pulmonar. MÉTODOS: estudio descriptivo de tipo caso control, doble ciego aleatorizado con 22 pacientes con tuberculosis pulmonar en terapia farmacológica y 22 controles sanos reclutados en los centros de salud Sebastián pagador y Alalay. Los pacientes fueron divididos aleatoriamente en dos grupos a los que se les administró zinc (45mg/día) o placebo durante tres meses. En todos los pacientes se tomó muestras de sangre antes y después de la intervención para medir pruebas de función renal y hepática. En los sujetos control la muestra de sangre se tomó al inicio del estudio para realizar las mismas determinaciones. RESULTADOS: no se encontró deferencias en la concentración de marcadores específicos de daño hepático o renal. CONCLUSIONES: la adición de un suplemento diario de 45mgr de zinc a la terapia 2RHZE/4HE no produjo daño renal ni hepático en las personas evaluadas.
Tuberculosis therapy with the 2RHZE / 4HE scheme comprises the administration for six months of rifampin, isoniazid, pyrazinamide and ethambutol, of which the first three are potentially hepatotoxic and exceptionally nephrotoxic. Tuberculosis produces depletion of the zinc concentration which increases the susceptibility to chronicity of the infection. OBJECTIVE: to evaluate the effect of co-administration of zinc and 2RHZE /4HE therapy on hepatic and renal function in patients with pulmonary tuberculosis. METHODS: a, descriptive case-control, randomized double-blind study. 22 patients with pulmonary tuberculosis receiving pharmacological therapy and 22 healthy controls recruited in the health centers Sebastián Pagador and Alalay. The patients were randomly divided into two groups. Who were given zinc (45mg / day) or placebo for three months. All patients were blood sampling before and after intervention to measure hepatic and renal functional tests. For the control subjects were blood sampling before the study to do the same test. RESULTS: no deference was found in the concentration of specific markers of hepatic or renal damage. CONCLUSIONS: the addition of a daily supplement of 45 mg of zinc to 2RHZE/4HE therapy did not cause hepatic, neither renal damage in the people evaluated.

Objective To investigate the influence of sevoflurane and total intravenous anesthesia with propofol on hepatic and renal function in elder patients under gastrectomy .Methods 55 patients between the ages of 60-75 ,ASA physical status class Ⅰor Ⅱ ,scheduled for an elective gastrectomy were randomly divided into two groups .Anesthesia was maintained with sevoflurane 1% -1 .2% and remifentanil (0 .1-0 .2)μg · kg -1 · min-1 in the group S and propofol (1 -2)mg · kg -1 · h-1 and remifentanil (0 .1-0 .2)μg · kg -1 · min-1 in the group T .The hepatic and renal function ,aspartate aminotransferase (AST ) ,alanine amin-otransferase(ALT),bloodureanitrogen(BUN)andcreatinineweretestedatpreoperation(baseline),postoperative1dayand3 days .Results AST was increased at postoperative 1 day and 3 day ,compared with that of the preoperation in the group S and group T .Serum BUN at 3 day and creatinine at 1 day and 3 day were significantly higher from the preoperative values in group S (P0 .05) .There were no significant difference in the AST ,ALT , BUN and creatinine between the groups(P>0 .05) .Conclusion The changes of hepatic and renal effect after inhalation anesthesia with sevoflurane and remifentanil and TIVA with propofol and remifentanil for gastrectomy are clinically insignficant ,and there is no difference between the two methods .
ABSTRACT
Objective To investigate the influence of blood arsenic concentration change on hepatic and renal function of rats administered with different toxic dosages of realgar by applying the linear mixed-effects model.Methods SD rats were given gastric gavage of realgar at the single dose of 3.738g/kg,1.869 g/kg and 0.935 g/kg respectively.After administration,the concentration of blood arsenic,the activities of urine alkaline phosphatase(AKP),N-acetyl-beta-D-glucosaminidase(NAG),serum glutamic oxaloacetic transaminase(GOT) and glutamate-pyruvate transaminase(GPT) activities,serum creatinine(Cr) level,and blood urea nitrogen(BUN) content were detected in different groups at different time points.The detection results were analyzed with the linear mixed-effects model.Results The changes of urine AKP and NAG activities,serum BUN content and serum GOT activity were presented in a dose-dependent manner,and had linear correlation with arsenic concentration.Conclusion In the dose range of 0.935 to 3.738 g/kg,realgar can cause the hepatic damage and the injury of tubular epithelial cells of kidney,but has not affected the renal excretion.
