The odontoid process of the ninety axis were measured to observe the morphological features in Koreans. The results are as follows. 1. Height of the ordontoid of process of axis was 14.1±1.3mm, and the degree of the height of the odontoid process to the height of axis was frequency of 38.2±2.6%. 2. Transverse diameter of odontoid process of the most axis (87.8%) was thinner at the lower part than at the upper part. And the difference of the thickness of upper part and lower part was 1.2±0.7mm. In anteroposterior diameter, lower part was thinner than upper part in frequency of 55.6%, and the difference of upper part and lower part was 1.0±0.5mm in the transverse diameter, 0.6±0.5mm in the anteroposterior diameter, therefore the thickness of the anteroposterior diameter. 3. The articular surface of the odontoid process of the axis articulating with the anterior arch of atlas was 8.9±1.7mm in the maximal length and 7.1±1.6mm in the maximal breadth.

Three freshwater snail species of the family Lymnaeidae have been reported from Korea, Radix auricularia coreana, Austropeplea ollula and Fossaria truncatula. Out of 3 lymnaeid snail species, A. ollula was naturally infected with the Echinostoma cinetorchis cercariae (infection rate = 0.7%). In the experiments with the laboratory-bred snails, F. truncatula as well as A. ollula was also susceptible to the E. cinetorchis miracidia with infection rates of 25% and 40%, respectively. All of three lymnaeid snail species exposed to the E. cinetorchis cercariae were infected with the E. cinetorchis metacercariae. It is evident that A. ollula acts as the first molluscan intermediate host of E. cinetorchis in Korea, and F. truncatula may be a possible candidate for the first intermediate host of this intestinal fluke. Also, three lymnaeid snail species targeted were experimentally infected with E. cinetorchis metacercariae.

This study was undertaken to know the extent of apoptosis, expression of bcl-2 and proliferating cell nuclear antigen (PCNA) in uterine cervical intraepithelial neoplasia (CIN; 15 cases) and invasive carcinoma (27 cases) and to evaluate them as a prognostic marker. Apoptosis was analysed by using the in situ apoptosis detection kit and bcl-2 and PCNA were detected by the immunohistochemical method. The results were as follows: Apoptotic indices (AI) in the invasive carcinoma (mean: 4.3) were 10-times higher than that in the CIN (mean: 0.43). Bcl-2 was expressed 60% of the cases in the dysplastic cells of the CIN II and CIN III, 33.3% of cases in the invasive carcinoma and not expressed in the CIN I except basal cells. The expression of the PCNA was increased by the grades of CIN and was strong in invasive carcinoma. The mean survival time of the patient with invasive carcinoma was significantly decreased in the higher AI index (above 4.3) than in the lower AI index (below 4.3). There was no significant correlation between the extent of apoptosis and the expression of bcl-2. According to the above results, AI are able to be used as an independent prognostic marker in the invasive cervical carcinoma, and bcl-2 and PCNA have an important role in the tumorigenesis of uterine cervical carcinoma.

Human papillomavirus (HPV) 16/18 is a causative agent of uterine cervical carcinoma. HPV 16/18 can alter cell cycle regulation through apoptosis. Bcl-2 is an important regulatory gene of apoptosis. A study was done to evaluate the relation between HPV 16/18 and bcl-2 and apoptosis in 21 cases of carcinoma in-situ (CIS), 5 cases of microinvasive carcinoma and 23 cases of invasive squamous cell carcinoma. HPV 16/18 was detected by hybrid capture system (HCS), bcl-2 protein by immunohistochemical method and apoptosis by using the hematoxylin-eosin stained slide. The results were as follows: Expression of the bcl-2 protein was 43% (9/21) in CIS and 26% (6/23) in invasive carcinoma. Expression of the bcl-2 protein was 42% (5/12) in CIS with HPV 16/18 infection, 44% in CIS without HPV 16/18 infection, 20% (2/10) in invasive carcinoma with HPV 16/18 infection and 31% (4/13) in invasive carcinoma without HPV 16/18 infection. Mean apoptotic index (mAI) was 3.36 in CIS, 5.23 in microinvasive and 6.25 in invasive carcinoma. mAI was 3.66 in CIS with HPV 16/18 infection, 2.86 in CIS without HPV 16/18 infection, 6.18 in invasive carcinoma with HPV 16/18 infection and 6.30 in invasive carcinoma without HPV 16/18 infection. Based on these results, we conclude that there are no correlation between HPV infection and bcl-2, and between HPV infection and apoptosis in invasive and in situ carcinoma of the uterine cervix, and apoptosis is increased according to tumor progression.

We report two cases of hyalinizing trabecular carcinoma (HTC) of the thyroid gland. These two patients were euthyroid women aged 36 and 65 years of age. The tumors were encapsulated and measured 0.8 and 4.0 cm in diameter, respectively. Histologically, the tumors were composed of a compact proliferation of cells in a lobular and trabecular pattern with an intervening hyalinized, fibrotic vascular stroma. Occasionally the cells were arrayed in microfollicles. Multiple and serial sections showed cords of tumor cells invading into the capsule in both cases and vascular invasion in one case. These findings suggested that HTCs are a malignant counterpart of hyalinizing trabecular adenoma, similar to conventional follicular tumor. Positive immunostaining of tumor cells for thyroglobulin and negative staining for high molecular weight cytokeratin, cytokeratin 19, neuron specific enolase, chromogranin, and synaptophysin allowed distinction from medullary carcinoma. Even though HTCs are an heterogeneous group of tumors, the present two cases are probably variants of follicular carcinoma rather than papillary carcinoma.

Chronic prostatitis has various symptoms and many problems in management. Recently a lipidosterolic extract of Serenoa Repens, Permixon has been reported to reveal potential antiandrogenic and anti inflammatory activities on prostate. Then we used Permixon on chronic prostatitis and following results were obtained. Permixon is administered orally in dose of 160mg., b.i.d. for 60 days in 31 cases of chronic prostatitis in 1st group, Permixon 160mg, with Cipro-floxacin 500mg, b.i.d. in 35 cases in 2nd group and Placebo 2 tablets, b.i.d. in 30 cases in 3rd group. In 1st group 36 cases(77.4%) were improved, 29 cases(82.8%) in 2nd group and 7 cases (23.3 %) of 3rd group were improved. Permixon is an effective drug in chronic prostatitis and there was no changes in laboratory findings and negligible side effects were noticed

Since the first report by Tansini in 1896, the latissimus dorsi muscle free flap has been widely used for various types of soft tissue defect due to reliable anatomy with a sufficient diameter of neurovascular pedicle and a sizable muscle. However, for relatively small soft tissue defect, latissimus dorsi free flap offers several distinct disadvantages of donor site including loss of the posterior axillary fold and flattening of the posterolateral chest wall, weakness of upper arm strength in extension, adduction and internal rotation. We treated three patients having various types of soft tissue defect using segmental latissimus dorsi muscular free flap depending on its descending branch of thoracodorsal neurovascular pedicles. There were no serious complications during 18 months of mean follow-up. We concluded that this method has some advantages such as no weakness of strength of the upper arm including walking on crutches, preserving the posterior axillary fold, preventing winging of the scapula and increased chance of using a flow-through technique. Here we present our cases of reconstruction of soft tissue defect using segmental latissimus dorsi free flap with a review of the literature.

This study was aimed to observe the effect of Anterior J hook headgear on the craniofacial structures in mixed dentition with Class II malocclusion. The laterial c-phalograms of 20' children treated by Anterior J hook headgear were traced, digitized and statistically analyzed. The results were as follows 1. Forward growth of maxilla was inhibited. 2. Rotational effect of maxilla was not observed. 3. There was distal movement of maxillary dentition. 4. Maxillary_.dentoalveolar growth changes were more effective in anterior portion than posterior portion. &.Mandible maintained a normal growth and mandibular plane angle- was maintained during treatment period. 6. The ratio of anterior facial height to posterior facial height was almostly not changed.

Myopericytoma is a benign tumor that is composed of myoid-appearing oval to spindle-shaped cells with a concentric perivascular pattern of growth. The tumor is morphologically heterogeneous and can exhibit a broad histologic spectrum. We describe a case of multiple myopericytoma occurring in the head and neck skin region with involvement of the parotid gland where it is known to occur very rarely. A 40-year-old woman noticed multiple enlarging, painless, round-shaped masses on her left cheek. The patient had experienced a similar lesion of the same area 8 years earlier which was completely excised and the pathological diagnosis was spindle cell type myoepithelioma. On a computed tomographic image, one mass involved the superficial parotid gland and was well encapsulated. Excision of the facial masses and superficial parotidectomy with facial nerve preservation were performed. A diagnosis of myopericytoma was established in light of the immunohistochemical pattern with the histopathological findings. Over the 4-year follow-up period, there was no evidence of recurrence. As many perivascular myoid neoplasms share common morphologic features with myopericytoma, we should consider the differential diagnosis, and confirm the histological findings with appropriate immunohistochemical staining. After identifying myopericytoma, it should be treated with wide surgical excision to prevent local recurrence.
