Congenital adrenal hyperplasia(CAH) results from an inherited defect in enzymatic steps required to synthesize cortisol from cholesterol. 21-hydroxylase deficiency accounts for 95% cases of CAH. We have analyzed CYP21 genes of CAH by PCR direct sequencing. Our results shows three cases of CAH owing to multiple mutations of CYP21 gene; first case, IVS2AS, A/G, -13, Ile172Asn; second case, IVS2AS, A/G, -13, Ile236Asn, Val237Glu, Met239Lys; third case, Ile172Asn, C to G at 1590nt, Val281Leu, Arg484Pro, G to A at 2697nt. Mutations such as Ile236Asn, Val237Glu, Met239Lys, and Arg484Pro are first noted in Korea.

OBJECTIVETo explore the risk factors of low back pain (LBP) among greenhouse vegetable planting farmers and estimate the level of the effects.

METHODSA self-made questionnaire based on the Dutch Musculoskeletal Questionnaire and the Nordic Questionnaire was conducted to 639 greenhouse vegetable planting farmers and then structural equation model was used to analyze the risk factors of LBP in SmartPLS software.

RESULTSThe coefficient of determination of the model was 0.827, and the structural coefficients of dynamic loads, static loads, force exertion, ergonomic environment and repetitive loads on LBP were 0.21, 0.43,0.27, 0.045 and 0.034 respectively, and the total effects of the above latent variables on LBP were 0.21, 0.43,0.27, 0.33 and 0.034 respectively.

CONCLUSIONThe main risk factors of LBP among greenhouse vegetable planting farmers were static loads, ergonomic environment, force exertion and dynamic loads.

Objective To study the morphological changes of diaphragm of rats with omethoate poisoning and the protection of penehyclidine hydrochloride.Methods The experimental model of Wistar rats was made by eliac injection ofomethoate,96 rats was divided randomly into four groups in average:the hrinematched control group (Group NO);the omethoate intoxication matched control group (Group PO);atropine and pralidoxime chloride cure group (Group AC); penehyclidine hydrochlofide and pralidoximc chloride cure group (Group PC).The whole blood cholinesterase (ChE) and creatinekinase (CK) activtitise were measured 2 h after poisoning.To observe the morphological changes of diaphragmat different time from 1 to 7 days.Results All the poisoned rats showed that the diaphragmatic histologic damage of the penehyclidine hydrochloride and pralidoxime chloride cure group was slighter than that of atropine cure group.Conclusion A possible reasons of the respiratory muscle paralysis conduced by AOPP was the putrescence of diaphragm muscle fiber, and penehyclidine hydrochloride could definitely protect the diaphragm of rats with omethoate poisoning,and we could deduce that it prevented from intermediate myasthenia syndrome.

Objective To evaluate the remote effect of local injection of botulinum toxin by use of the F-wave measures. Methods The F-wave responses as well as M-waves were recorded before injection, and at 1 week,12 to 24 weeks after local injection of botulinum toxin type-A (BTX-A) in 26 patients, including 19 with hemi-facial spasm (HFS),5 Meige syndrome and 2 torticollis spasmodicus (TS).The following parameters were analyzed: M-wave latency (ML) and amplitude (Mamp), F-wave minimal latency(Fmin) and average latency(Fave),amplitude (Famp), duration (Fdur), persistence (Fper) and chronodispersion (Fchr). The above parameters were obtained through the electric stimulation of ulnar and tibial nerves, and recorded from the abductor digiti minimi and extensor digitorum brevis, respectively. Results No definite F-wave was obtained by electric stimulation of ulnar nerve at 1 week after injection in 3 HFS patients (5 nerves). The Fave recorded from electric stimulation of ulnar and tibial nerves prolonged significantlyand Fdur from ulnar nerve increased significantly at 1 week after injection, but were not significantly different from those of pre-injection when recorded at 12 to 24 weeks after injection. No significant correlation of the altered F-wave parameters was found with the dosage of BTX-A. Conclusion Fdur and Fave could sensitively assess the remote effect of the local injection of BTX-A, the remote effect might be correlated with the distance between injected muscle and tested muscle, rather than the dosage of BTX-A.
