OBJECTIVE: Many cases of fertilization failure after ICSI is attributed to decondensation defect of sperm head, therefore, selection of sperm with well-condensed, fully-matured nucleus is critical for successful fertilization. During mammalian spermiogenesis, replacement of the somatic histones by protamines allows normal sperm nuclear condensation. The degree of condensation can be shown with the aid of acidic aniline blue staining, which is able to discriminate between lysine-rich histones and arginine- or cysteine-rich protamines. The objective of this study was to investigate the possible relation between nuclear maturity of human sperm and hypo-osmotic swelling patterns. Hypo-osmotic swelling test is very simple and convenient test to measure functional integrity of human sperm membrane, and each already tested sperms can be used for fertilization. METHODS: For assessment of sperm nuclear maturity, aniline blue staining was performed on the slides, already undergone hypo-osmotic swelling test in 5 subfertile patients with abnormal semen parameters and 8 fertile donors. After 3 hours swim-up, these procedures were repeated in each cases. RESULTS: Sperms with negative aniline blue were significantly increased after swim-up in each group. There was a significant increase in the proportion of negative aniline blue in sperms with swelling patterns(e+f+g) compared to sperms with non-swelling patterns(a), except swim-up group in subfertile patients. CONCLUSION: Choosing the swelling patterns, rather than non-swelling sperms after hypo-osmotic test may be beneficial for the selection of sperms with well-condensed, mature nucleus and intact membrane.

Adrenal cortical carcinoma is a rare disease both in adults and in children. Most of these tumors are functional, especially in children, producing endocrine syndromes such as virilization, Cushing syndrome, hyperaldosteronism or feminization. We experienced a case of adrenal cortical carcinoma in a 7yr old boy who showed features of virilization such as rapid growth rate, penile enlargement, and pubic hair. This case was diagnosed with typical hormonal findings and abdominal MRI and confirmed by pathologic findings. He was successfully treated by total left adrenalectomy and has been followed up without problem over eight months.

OBJECTIVES: The aim of this study was to evaluate the psychological characteristics of the patients with bruxism by Minnesota Multiphase Personality Inventory(MMPI). METHODS: MMPI was administered to 87 patients(46 bruxism group and 41 control group) who had visited a local dental clinic from January to August 1998. RESULTS: The bruxism group had a higher score than control group in Masculinity-Femininity(Mf) scale. There were no differences between bruxism group and control group on the distribution of Depression(D), Psychopatic Deviate(Pd), Paranoia(Pa), Psychasthenia(Pt) scales. The bruxism group with the family history showed higher score than the bruxism group without family history in Pd scale. Male bruxism group had a higher score than female bruxism group in Defensiveness(K) scale and female bruxism group had higher score than male bruxism group in Pa scale. The bruxism group of clenching type had higher score than the bruxism group of mixed type in Social Introversion(Si) scale. There were no differences in MMPI score between those who had and did not have symptoms such as masticatory musle pain, neck pain and headache. CONCLUSION: It is concluded that individualized approach may be effective to the evaluation of psychological disturbances which might be related to sex, family history and, type of bruxism, while we did not find significant differences in personality charateristics between the bruxism and control groups.

Histopathological diagnosis of brain stem glioma should be performed for the purpose of the determination of its management and clinical course, but its surgical biopsy has been followed by high mortality and morbidity. We performed the tissue sampling for histological examination with BRW stereotaxic system under local anesthesia successfully.

A number of recent reports have described the usefulness of the epidural injection of narcotics for the relief of postoperative pain. But the epidural use of narcotic agonist-antagonist, nalbuphine hydrochloride, has not been reported. To study the effect of epidural nalbuphine hydrochloride for postoperative pain relief, we divided 73 patients into 5 groups randomly: 3 mg nalbuphine hydrochloride in 10 ml saline (group 1, n=9); 4 mg nalbuphine hydrochloride in 10 ml saline (group 2, n=14); 5 mg nalbuphine hydrochloride in 10 ml saline (group 3, n=21); 3 mg morphine in 10 ml saline (group 4, n=16); 4 mg morphine in 10 ml saline (group 5, n=13). The results were as follows 1) The onset time of analgesic effect were average 15~20 minitues in all groups 2) The durations of analgesia of epidural nalbuphine groups were (average; 5~7 hours) significantly shorter than morphine groups (average; 31~32 hours). 3) The degree of analgesia were same between 5 groups 4) The complications were nausea, vomiting and pruritus in all groups, but the frequency of pruritus in morphine groups was more than nalbuphine groups (p<0.05). 5) Urinary retention was observed only in morphine groups. In conclusion, the result of our study suggests that nalbuphine hydrochloride be better agent than morphine in terms of complication for postoperative pain relief but the duration of action is shorter than morphine, when injected epidurally.
