In Liaoning Province in northeastern China, we found a G6PD-deficient patient at the age of 3. By the classification of the World Health Organization, this patient was categorized as class I (very severe G6PD deficiency). When we investigated the G6PD gene of the patient, we found that he had a replacement of G to A at nucleotide 1339. As a result, the amino acid at position 447 should change from Gly to Arg. This replacement is known as G6PD Santiago de Cuba, because it was first discovered in a Cuban boy who showed heavy chronic anemia. Today, 28 G6PD variants have been reported in the Chinese population, and all are categorized as class II (severe deficiency) or class III (mild deficiency);in class II or III deficiency, anemia is not present in daily life, but hemolytic attack can occur when the carrier ingests certain oxidative medicines or foods. This is the first report of a G6PD-deficient Chinese patient in the category of class I. We intended to find other G6PD-deficient cases in northeastern China and tested several hundred blood samples, but no cases of G6PD deficiency were found (0/414). In central China, where falciparum malaria was endemic from the 1950s to 1970s, we found two G6PD-deficient cases (2/27) and the other members from their families whose variant type was G6PD Kaiping (1388GT), which is a common variant in the Chinese population.

We biomechanically evaluated the bone fixation rigidity of an ONI plate (Group I) during fixation of experimentally created transcondylar humerus fractures in cadaveric elbows, which are the most frequently observed humeral fractures in the elderly, and compared it with the rigidity achieved by 3 conventional fixation methods:an LCP reconstruction plate 3.5 using a locking mechanism (Group II), a conventional reconstruction plate 3.5 (CRP) with a cannulated cancellous screw (Group III), and a CRP with 2 cannulated cancellous screws (CS) in a crisscross orientation (Group IV). In the axial loading test, the mean failure loads were:Group I, 98.9+/-32.6;Group II, 108.5+/-27.2;Group III, 50.0+/-7.5;and Group IV, 34.5+/-12.2 (N). Group I fixations failed at a significantly higher load than those of Groups III and IV (p0.05). In the extension loading test, the mean failure loads were:Group I, 34.0+/-12.4;Group II, 51.0+/-14.8;Group III, 19.3+/-6.0;and Group IV, 14.7+/-3.1 (N). Group IV fixations showed a significantly lower failure load than those of Group I (p0.05). The fixation rigidities against mechanical loading by the ONI plate and LCP plate were comparable. These results suggested that an ONI system might be superior to the CRP and CS method, and comparable to the LCP method in terms of fixation rigidity for distal humerus fractures.

The aim of the present study was to evaluate the effects of three different anti-androgenic drug-therapy regimens, Diane 35 (cyproterone acetate (CPA) [2 mg] and ethinyl estradiol [35 microg]) plus CPA, Diane 35 plus spironolactone, and spironolactone alone, in patients with hirsutism. In this prospective, randomized clinical study, 79 subjects with idiopathic hirsutismus were studied. The patients were divided into 3 groups. Group I patients (n=32) were treated with Diane 35 plus CPA, group II patients (n=25) with Diane 35 plus spironolactone [100 mg], and group III patients (n=22) with spironolactone [100 mg] alone. Serum FSH, LH, testosterone (T), and DHEAS levels were analyzed before and after treatment at 6 and 12 months. Hirsutism scores were graded according to the Ferriman-Gallwey scoring system, and side effects were monitored. All treatment regimens were found to be efficient and well-tolerated, and none of the patients stopped therapy due to any adverse event. However, in hormone screening, only patients on the Diane 35 plus CPA regimen revealed a decrease in serum T levels after therapy. As such, treatment of each hirsute patient should be planned individually, but with regard to both cost-efficiency and potential side effects, we recommend spironolactone alone in the treatment of hirsutismus.

1) Normal karyotype of Donryu strain rat was determined according to the classification of KURITA et al. (8). Namely, the number of chromosomes was 42 in diploid cells, and chromosomes were divided into 3 groups (A, B and C) according to the position of centromere. A.group was consisted of 7 pairs of metacentric chromosomes, B-group 4 pairs of sub· meta.subtelocentrics and C.group 10 pairs of telocentrics and Y. 2) Among all chromosome pairs a pair of the longest telocentric chromosomes (C.l), 4 pairs of all the B.group, and the Y chromosome were recognizable. 3) The presence of polymorphism was demonstrated in the smallest submetacentric chromosomes (BA),: namely, (I) a homologous submeta. centric pair, (II) a homologous subtelocentric pair and (III) a heteromor. phic submeta and subtelocentric pair which seemed to be a hybrid from (I) and (II). To distinguish the polymorphism in their genotype from phenotype was impossible. 4) Animals with type III B·4 chromosomes were produced by type I and type II animals. 5) By checking the chromosomes of the inbred Donryu strain rats maintained over 40 generations by brother.sister mating at Nihon Rat Co., polymorphism in BA chromosomes was also recognized.

Female Cb mice weighing 20-23 g were exposed to 800 ppm (in average) of 1, I, 2, 2.tetrachloroethane for 3 hours. Both triglyceride and phospholipid in the liver and plasma were determined at varying times after the exposure. On the other hand, there were observed the ultraviolet absorption spectra of microwmallipids in the liver at 90 minutes after the 1, 1,2, 2-tetrachloroethane or the carbon tetrachloride exposure. The results thus obtained are summarized as follows: 1. The increase of hepatic triglyceride contents attained the maximum level in the period between 20 and 25 hours after the exposure and declined to the initial levels at 90 hours later. 2. The plasma triglyceride levels decreased until 25 hours after the exposure, then tended to increase significantly and were much higher than the control levels in the period between 70 and 90 hours later. 3. Both liver and plasma phospholipid levels decreased gradually up to 25 hours after the exposure, then slowly recovered with almost the same rate of increase. 4. It was suggested that the inhalation of the above vapors induced a little change in microsomal lipids in the liver.
