Objective: This study was designed to evaluate the effects of endogenous LH surge, GnRH agonist (GnRH-a) or human chorionic gonadotropin (hCG) as ovulation trigger on pregnancy rate by intrauterine insemination (IUI). Method: Patients received daily 100 mg of clomiphene citrate (CC) for 5 days starting on the third day of the menstrual cycle followed by human menopausal gonadotropin (hMG) for ovulation induction. Follicles larger than >16 mm in diameter were present in the ovary, frequent LH tests in urine were introduced to detect an endogenous LH surge. Final follicular maturation and ovulation were induced by GnRH-a 0.1 mg (s.c.) or hCG $5,000{\sim}10,000$ IU (i.m.) administration except natural ovulation. Pregnancy was classified as clinical if a gestational sac or fetal cardiac activity was seen on ultrasound. Results: There were no differences in age, duration of infertility and follicle size, but more ampules of hMG were used in GnRH-a group compared to hCG 10,000 IU treated group (p<0.05). Lower level of estradiol ($E_2$) on the day of hCG or GnRH-a injection was observed in hCG 10,000 IU group than other treatment groups (p<0.01). The overall clinical pregnancy rate was 19.8% per cycle (32/162) and 22.2% per patient (32/144). Pregnancy rate was higher in natural-endogenous LH surge group (37.5%, 9/24) than GnRH-a (18.8%) or hCG treated group (20.9% & 13.9%), but this difference was not statistically significant. No patient developed ovarian hyperstimulation. Abortion rate was 22.2% (2/9) in hCG 5,000 IU group. Delivery or ongoing pregnancy rate was 37.5% (9/24), 18.8% (3/16), 16.3% (7/43) and 13.9% (11/79) in endogenous LH surge, GnRH-a, hCG 5,000 IU and hCG 10,000 IU treatment groups, respectively. Conclusion: These results support the concept that use of natural-endogenous LH surge in stimulated cycles may be more effective to obtain pregnancies by IUI than GnRH-a or hCG administration.

결정성 aluminosilicate 광물의 일종인 천연 zeolite는 광물학적 특성과 화학적 표면활성으로 인하여 다방면의 공업화학적 이용가치가 매우 높고 광물중 특히 가장 높은 양이온교환능을 가지고 있어 기체분자에 대한 선택적 흡착력이 큰 molecular sieve로써 흡착분리제로는 물론, 건조제, 흡습제, 이온교환체, 촉매, 증량제 그리고 폐수처리제, 경수의 연화제등으로 이용도가 날로 증가하고 있다. 국내산 천연 zeolite를 IN HCL용액과 NaCl용액으로 화학처리하여 다공성을 증가시켜 column충전제로 사용한 결과, 혼합기체 Ar, $N_2$ CO및 $CH_4$의 분리특성에 관해서 HCL용액으로 처리한 mordenite 시료는 활성화온도가 $300^{\circ}C$일 경우, CO와 $CH_4$의 분리는 곤란하나 $350^{\circ}C$에서는 분리가 용이하였고 NaCl용액으로 처리한 시료는 미처리한 것과 거의 유사하였다. Ar과 $N_2$와의 분리에는 산 또는 알칼리로 화학처리한 시료에도 별로 효과가 없었으나 HCL용액과 NaCl용액을 연속적으로 처리한 천연 zeolite는 합성 zeolite의 특성에 견줄만한 정도로 기체분리효과와 HETP값을 보여주었다. 한편 시료의 화학처리에 의한 Ar과 CO의 흡착열의 변화는 극성기체인 CO의 경우, 별로 변화가 없지만 무극성기체인 Ar은 영향을 받기가 용이하였다. 또한 carrier gas He의 유속이 대략 20~30ml min범위일때 최소의 HETP값을 가지며 column의 효능이 좋았다.

Fibromatosis is benign fibroblastic proliferative lesion with abundant collagenous neo-formation located principally in the abdominal wall and in the upper and lower extremities (Masson & Soule, 1966). Wilkins and Waldron, in 1975, suggested that the title aggressive fibromatosis was a more appropriate term, reflecting the invasive characteristics of the disease. Synonyms listed were extra-abdominal desmoid, juvenile fibromatosis, aggressive infantile fibromatosis and congenital fibrosarcoma. A total of 12% of all fibromatosis arise in head and neck. Fibromatosis of the oral cavity is uncommon and is even more rare when in involve the mandibule. It is a locally aggressive fibrous tissue tumor, generally does not metastasize, but may cause considerable morbility and even death due to local infiltration. The degree of microscopic cellularity is variable, not only from tumor to tumor but also from area to area in the same tumor. Some tumors present with proliferation of mature fibroblasts and a dominating collagenous component : others may show a lack of the tumor in both types. The common histologic denominator appears to be cellular interlacing bundles of elongated fibroblasts, showing little or no mitotic activity and no pleomorphism. Mitosis are not a consistent index of malignancy when found in younger age groups. Fibromatosis still posses difficult problems of diagnosis and treatment. It is frequently recurrent and infliltrates neighbouring tissues. These lesion infliltrate widely and replace muscle, fat, and even bone with fibrous tissue of varying cellularity. Lesion representing fibromatosis in the oral cavity must be carefully evaulated by both surgeon and pathologists to ensure proper diagnosis and treatment planning. When these lesions involve bone, surgeon must be aware of the lesion's potential to perforate the cortex and expand while remaining hidden from the surgeon's view. Careful and precise clinical correlation with histologic appearance is essential to preclude misdiagnosis of fibrosarcoma yet provide surgical treatment plan that provides adequate local excision and long-term follow up. As regards cause, little is known. It is attributed to trauma or alteration in the sex hormone(Carlos, et al, 1986). Clinially, the lesion is reported to be not painful in most cases, but capable of rapid growth. The treatment is essentially surgical excision with wide margin of adjacent uninvolved tissue. Radiotherapy, hormone treatment or chemotherapy are of no use (WIkins et al, 1975 ; Majumudar and Winiarkl, 1978). We report a case of aggressive fibromatosis of 15-year-old with a lesion in the soft tissue of the parotid area that invaded the underlying bone of the mandibular body.

Introduction: The aim of the present study was to investigate the effect of mechanical irrigation in combination with mouthwash of antimicrobial agents on salivary bacterial counts. Materials and Methods: This study was performed with a randomized study employing a panel of 40 healthy volunteers (20 males and 20 females) between the age of 26 and 32 years. Volunteers were randomly put in one of four treatment groups. In the first group, 0.2 mL of non-stimulatory saliva was collected from every subjective person. Then, saliva was collected after rinsing with chlorhexidine (CHX) for 1 minute. In the second group, non-stimulatory saliva was collected, and then saliva was collected after rinsing with CHX and irrigation with saline. In the third and fourth groups, the same procedures as the first and second groups were performed with povidone iodine (PVI) instead of CHX. All of these samples were cultured for 48 hours aerobically. The reduction rates of colony-forming units (CFU) were calculated for each group. The reduction rate between each group was tested statistically using student t-test. Results: Using CHX in combination with saline irrigation showed a significant decrease of the salivary bacterial CFU when compared with only using CHX.(P<0.01) And using PVI with saline irrigation showed a little decrease of the CFU when compared with only using PVI, but there was no statistical significance.(P>0.01) Conclusion: It was concluded that the CHX or PVI used with saline irrigation made the salivary bacterial counts reduced more than when CHX or PVI was used alone as an oral antiseptic agent.

The ulnar nerve extends down the arm, across the elbow, and into the hand. It provides sensation to the little and ring fingers and activates many of the small muscles in the hand. The determination of peripheral nerve conduction velocity is an important part of ulnar nerve evaluation. The electrodiagnostic value as neurophysiologic investigative procedure has been known for many years but normal value of digital nerve was not reported in Korea. The purpose of this investigation was to measure the digital nerve conduction velocity of ulnar nerve for obtain clinically useful reference value and compare difference in each fingers and then compare with the other countries. 71 normal Korean volunteers (age, 19-65 years; 142 hands) examined who has no history of peripheral neuropathy, diabetic mellitus, chronic renal failure, endocrine disorders, anti-cancer medicine, anti-tubercle medicine, alcoholism, trauma, radiculopathy. Nicolet Viking II (EMG machine) was use for detected conduction velocity and amplitude of digital nerves in ulnar nerve. Data analysis was performed using SPSS. Descriptive analysis was used for obtain mean and standard deviation and independent t-test was used to compare with ring and little finger. Conduction velocity of the right ring finger was 57.44m/sec and little finger was 55.32msec. The left ring finger was 55.55msec and little finger was 54.11msec. Amplitude of the right ring finger was $30.28{\mu}V$ and little finger was $48.36{\mu}V$. The left ring finger was $30.67{\mu}V$ and little finger was $52.76{\mu}V$. There were significantly difference between ring and little in amplitude (p<.05) but there were no statistically difference between conduction velocity of ring and little finger (p>.05). The amplitude of little finger are greater than ring finger. The present results revealed that electodiagnosis can easily perform in little finger for digital nerve of ulnar nerve study.

본 연구에서는 여러 소아정신과 장애를 보이는 아동들의 모(母)의 MMPI 프로파일 유형을 비교, 분석함으로써 모(母)의 성격 특성이나 심리적 문제와 아동의 정신과적인 장애간의 관계를 알아보고자 하였다. 서울대학 병원 소아정신과를 방문한 아동들을 그들이 보이는 문제 행동의 유형에 따라 내면화중상 집단(n=35), 외현화증상 집단(n=35), 발달 장애 집단(n=21)으로 분류한 후, 이러한 임상 집단의 모(母)들과 정상 아동 집단의 모(母)들(n=20)이 본 연구의 피험자로 사용되었다. 4집단의 모(母)들의 MMPI결과를 5가지 프로파일 유형(정상, 우울증, 불안 장애, 신체화 장애, 성격장애)으로 분류하여 아동의 진단과 틀의 MMPI 프로파일 유형간의 관계를 알아본 결과, 아동의 진단과 모(母)의 MMPI프로파일 유형간에 유의미한 관계가 있었다. 정상 아동들의 모(母)는 대부분 정상 프로파일을 보인 반면, 임상 집단의 모(母)들은 아동의 진단과는 관계없이 통계적으로 유의미한 수준에서 우울증을 시사하는 프로파일을 많이 보였고, 외현화증상 집단의 모(母)들이 내면화 증상 집단의 모(母)보다 더 불안 장애 프로파일을 많이 보였다. 이러한 결과는 아동의 정신과적인 문제와 모(母)의 심리적 장애간에 관련이 있음을 시사하는 것으로, 아동과 모(母)의 부정적인 상호작용이 서로의 심리적인 적응에 해로운 영항을 주었을 가능성이 논의되었고, 정신병리에 대한 연구에서 부모가 아동의 적응에 미치는 영향뿐만 아니라 아동의 문제가 모(母)의 심리적 적응에 미치는 특별한 영향도 살펴볼 필요가 있음이 시사되었다.

본 연구에서는 청소년 정신과 환자군중에서 우울증 집단(n=19), 우울증적 품행장애 집단(n=13), 정신분열증 집단(n=10)을 대상으로 자아기능의 장애정도를 비교하였다. Rorschach검사를 통해 자아손상지표(EII)를 도출하였고, 요인분석 결과 선행연구와 마찬가지로 자아손상의 단일요인을 얻었으며 전체 변량의 57.18%를 설명하였다. EII를 진단별로 비교했을 때, 정신분열증 집단이 다른 두 집단에 비하여 유의미하게 높은 EII 점수를 나타냈지만, 우울증 집단과 우울증적 품행집단간의 차이는 발견되지 않았다. 이상의 결과는 자아기능 장애정도에 대한 측정도구로서 EII가 청소년정신장애집단에서 사용하는데 유용하다는 것을 제시함과 동시에, 청소년기 우울증적 품행장애가 이른바 위장된 우울증에 해당될 가능성을 시사해주었다.
