[Determination of glycosides in traditional Chinese medicine liu-wei di-huang by RP-HPLC].

OBJECTIVE: To establish a RP-HPLC method for determination of glycosides in Traditional Chinese Medicine Liu-wei Di-huang. METHOD: The samples were analyzed on an ODS column at 30 degrees C, with mobile phase of methanol/water (33:67) at flow rate 1.0 mL.min and detection at wavelength of 236 nm. RESULT: Three major components reached base-line separation and were identified to be mononiside, loganin, paeoniflorin. Respectively for the three components, linear correlations were found between peak areas and concentrations in the ranges of 7.4-60, 7.7-62 mg.L-1 and 8.5-68 mg.L-1, and the recoveries were 98.8%, 98.3%, 99.6%. CONCLUSION: The established method is proved to be suitable for simultaneous quantification of three major glycosidic components in Liuwei Dihuang decoction and can be used for evaluation of the quality of Liuwei Dihuang preparations.

[Experimental study on effect of the water extract of dogwood fruits on the liver and testis in rats model of kidney-yang deficiency].

OBJECTIVE: To explore the effect of Dogwood fruits on tonifying kidney-yang. METHOD: The effect of the water extract of Dogwood fruits on rats model of kidney-yang deficiency with the hydrocortisone was observed. RESULT: The water extract of Dogwood fruits could make normal the liver weight, and mitigate hepatocyte pathologic changes, increase the heptocellular levels of RNA and hepatin, and decrease the malondialdehyde (MDA) in rats model of kidney-yang deficiency. It could also make the viscera quotiety return to normal way and increase the levels of RNA in the interstitial cells of testicle in rats model of kidney-yang deficiency. CONCLUSION: Water extract of Dogwood fruits can protect and improve the functions of the liver and testicle in rats model of kidney-yang deficiency.

[Determination of ursolic acid of Liuwei Dihuangwan simulation samples by NIR].

OBJECTIVE: Determine the content of ursolic acid of Liuwei Dihuangwan. METHOD: Using NIR with PLS, PCA-BPANN and WT-BPANN. RESULT: The predication recovery were 100.7%, 100.6%, 100.1%, and the RSD were 5.42%, 6.49%, 6.52% respectively. CONCLUSION: NIR can be used in the determination of ursolic acid, which set up the foundation of on-line control of traditional Chinese medicine.

[Apropos of 100 cases of malaise in infants].

Among 4,411 children hospitalized from May 1985 through April 1987, 100 infants (mean age three months) had exhibited an apparently life-threatening event. Management included careful history taking by interviewing parents, a thorough physical evaluation, routine laboratory tests, and cardiorespiratory monitoring. A variety of further investigations were usually performed to look for gastroesophageal reflux (GER), vagal hyperreflectivity, or sleep-related cardiorespiratory disorders. Leading causes, that often occurred in combination, included GER (66 per cent of cases), and vagal hyperreflectivity (13%). Atypical breath-holding spells, ENT causes, and neurological causes were documented in 8%, 6% and 5% of cases respectively. Medical treatment of the GER proved effective in 90% of cases. Metoclopramide (Primperan, 10 drops/kg/d) was effective in 62% of infants with GER and was well tolerated. Diphemanil methylsulfate (Prantal, 10 mg/kg/d) satisfactorily controlled vagal hyperreflectivity. Monitoring was prescribed in 43% of cases.

[Dwarfism, arterial hypertension and hyperkalemic acidosis corrected with thiazides. A case of type II pseudohypoaldosteronism].

BACKGROUND: Type II pseudohypoaldosteronism is a rare tubulopathy defined by abnormal renal potassium excretion. CASE REPORT: A 12 1/2 year-old girl, was admitted for dwarfism. Her parents were not consanguineous and her 5 living sibs were normal. At admission, she had moderate hypertension: systolic 130-150 mmHg; diastolic 80-100 mmHg and no pubertal development. LABORATORY DATA: pH (arterial): 7.34; bicarbonates: 18-20 mEq/l; chloride: 112-120 mEq/l; potassium: 5.6-7 mEq/l; aldosterone: 200-700 pg/ml (N < 60); plasma renin activity: 0.4 ng/ml/hr (N 2.2 +/- 0.2). The bone maturation was 8 1/2 years. All the other renal function tests were normal. The titratable acidity was 22 mEq/day (N 20-40) and the ammonia excretion 15.2 mEq/l (N 44-61). The fractional excretion of potassium was 6.5% (N 11.8 +/- 1.9). This girl was given polystyrene sulfonate resin followed by hydrochlorothiazide (1 to 3 mg/kg/day). There was a subsequent improvement in all data, a growth spurt and pubertal development. CONCLUSION: This is the fifth case of type II pseudohypoaldosteronism reported in childhood and the first one with hypertension. The beneficial effect of hydrochlorothiazide is underlined.

[Study of risk factors for recurrence in severe life-threatening conditions in infants].

In a prospective study, 180 infants, mean age 2-6 months, hospitalized for apparent life threatening events between October 1985 and September 1988 (for 7,261 infants admitted into the pediatric unit during the same period), were submitted to the following investigations: careful anamnesis, complete clinical examination, systematic paraclinical investigations (standard biological studies, infectious and metabolic tests, investigations for gastro esophageal reflux (GER) and vagal hyper-reflectivity (VHR), polysomnography) or adapted to the clinical situation (toxic tests, brain computed scan, laryngoscopy, etc). Pathologies were mainly functional with neuro-vegetative immaturity (67.5%): gastro esophageal reflux (49%), vagal hyper-reflectivity (8.5%) or both (10%). An incidental pathological factor (breath holding spell, convulsion, intoxication, infection) was found in 18.5% of the infants, and 14% had normal results. Diphemanil 10 mg/kg/24h corrected the VHR and Metoclopramide 1 mg/kg/24h controlled 52% of the GER. The recurrence rate of illness in the GER and VHR groups was statistically lower with efficient therapy (12% vs 48%); no recurrence occurred in other groups.
