It is generally accepted that tbe lepromin test is of great value in the type classification and the evaluation of the prognosis of leprosy. But the nature of the antigenicity in lepromin reaction stiIl remains uncertain. The present study was carried out to investigate the antigenic characteriatics of the early(Fernandez) and the late (Mitsuda) reactions to Mitsuda lepromin antigen. Mycobacterium leprae was purified by trypsin digestion from human lepromas, and was broken down by passing 5 times through a French Pressor at 16, 000 p.s.i.. From the broken cell suspension, cell wall, cytoplasm, very low density lipoprotein (VLDL) and lipopolysaccharide (LPS) were prepared. IntradermaI skin tests were perforrned on 30 leprosy patients classified according to the Ridley-Jopling scale (4 TT, 6 BT, 2 BB, 7 BL and 11 LL), with 0. 1ml of the Mitsuda lepromin(intact cells) broken cells, cell wall, cytoplasm, VLDL and LPS antigens. Readings for the early and the late reactions were done 72 hours and 28 days, respectively, after itradermal injections of the above antigens. The results are summerized as follows: 1, Early reactions were elicited by broken cells, cell wall and cytoplasm in all of the patients who could react to Mitsuda lepromin antigen. VLDL and LPS antigens could also elicit early reactions in 9(56)% and in 14(88%), respectively, of the 10 patients who showed positive reaction to Mitsuda lepromin antigen. These results mean that the early reaction may be due to multiple antigena, originated either from M. leprae or from contaminated human tissues. 2. Late reactions were elicited by broken cells and cell wall antigens, but not by cytoplasm antigen, in all of the patients who showed late reactions to Mitsuda lepromin antigen. These results mean that broken cells also produce a late reaction and the specific antigen(s) of the late reaction may reside in the cell wall fraction of the M. leprae.

Bladder mucosa has been reported as an excellent tissue for construction of a neourethra. We used bladder mucosa in 3 cases when there was inadequate foreskin to create a neourethra. Two cases were penoscrotal hypospadias with chordee which were repaired in one stage operation and one case was scrotal hypospadias with severe chordee which was repaired in two stage operation. The. sizes of harvested bladder mucosa were 4x 1.5cm, 10 x 3.5cm and 15 x 3cm respectively. Two minor and one major complications occurred. The minor complications were urethral stricture in one case which was managed with urethral dilation and penile swelling after self-voiding in one case which required urinary diversion for several days. In one case severe problem with entire neourethra stricture necessitated internal urethrotomy and intermittent urethral dilatation. In all cases sufficient graft tissue could be obtained and there were no urethrocutaneous fistulas. Thus, the use of bladder mucosal graft in hypospadias repair is feasible in cases in which previous repairs have railed or in which sufficient foreskin for neourethral reconstruction is lacking.

Magnetic resonance imaging(MRI) is accepted as a useful tool for the diagnosis of injury of the knee recently. The anterior cruciate ligament tear is accompanied by the damage of the osseous and soft tissue of the knee. The occult osseous lesion is found on magnetic resonance imaging as bone density change that is not found on the simple radiograph. From Jan. 1992 to Apr. 1994, magnetic resonance imaging was performed on 44 patients with acute anterior cruciate ligament tears. MRI was done within 6 weeks of the index anterior cruciate ligament injury. The criteria of decreased signal intensity on the Tl weighted image and increased signal intensity on the T2 weighted image was applied for the incidence assessment of the occult osseous lesion. After arthroscopy with or without ACL reconstruction, follow-up simple radiograph was checked every 3 months. Occult osseous lesions were documented in 32(73%) of the 44 patients. Of the 32 patients with bony lesion, 81% had lesions of the lateral compartment. Lateral femoral condyle was involved in 15 cases(46.9%), and lateral tibial plateau in 22 cases (68.8%). Follow-up X-ray revealed no joint deperession in all of the 32 patients with the occult osseous lesion. This result suggests that there is a high correlation between the occult osseous lesion of lateral compartment of the knee on magnetic resonance imaging and anterior cruciate ligament tear. The presence of the occult osseous lesion in the patient with acute anterior cruciate ligament tear did not affect rehabilitation and weight bearing.

In general, reverse shoulder arthroplasty revision is performed using the same implant for both the humerus and glenoid components. However, the authors of the present case used different implants from what was used previously for treating instability with scapular notching and glenoid aseptic loosening and report the case.

The bone mineral density(BMD) of the lumbar spine (L2L4) was measured by using dual energy x-ray absorptiometry(Norland M6 DEXA) in 80 children aged between 2months and 15years (group I:2monthlyears, group 2: 1year5years, group3:6years10years, group4*: 11years15years). The correlation coefficient of BMD with age, body weight, height and Tanner stage were 0.696, 0.693, 0.717 and 0.636 respectively. There were sigificant difference. in BMD(g/cm2) between-group 1(BMD : 0.335 0.175) and group 2(BMD : 0.627 0.200), and group 3(BMD : 0.714 0.189) and group.4(BMD : 0. 8730.163) (P<0.05). There was no significant difference of BMD between boys and girls(P<0.05). BMD also increased significantly with development of Tanner stages(Tanner stage 1 : 0.547 0.234, Tanner stage 2 : 0.783 0.136, Tanner stage 3 : 0.998 0.080) (P<0.05). These data indicate that the BMD was correlated with age, body weight, height and Tanner stage significantly and BMD increased significantly during growth spurt occured in 1 to 4years of age and puberty.
