Background: The polycystic ovary syndrome (PCOS), characterized by hyperandrogenism and chronic anovulation, is a common endocrine disorder in women. PCOS, which is associated with polycystic ovaries, hirsutism, obesity and insulin resistance, is a leading cause of female infertility. In this condition there is an imbalance in female sex hormones. All the sequelae symptoms of PCOS gradually lead to cancer in the course of time. It is heterogeneous disorder of unknown etiology so it is essential to find the exact cause. Materials and Methods: In this study both invasive and non-invasive techniques were employed to establish the etiology. Diagnosis was based on Rotterdam criteria (hyperandrogenism, ovulatory dysfunction, PCOM) and multiparameters using buccal samples and dermatoglypic analysis and cytogenetic study for 10 cases and four age and sex matched controls. Results: In clinical analysis we have observed the mean value of total testosterone level was 23.6nmol/L, total hirsutism score was from 12-24, facial acne was found in in 70% patients with 7-12 subcapsular follicular cysts, each measuring 2-8 mm in diameter. In dermatoglypic analysis we observed increases in mean value ($45.9^{\circ}$) of ATD angle when compared with control group and also found increased frequency (38%) of Ulnar loops on both fingers (UU), (18%) whorls on the right finger and Ulnar loop on left finger (WU) and (16%) arches on right and left fingers (AA) were observed in PCOS patients when compared with control subjects. Features which could be applied as markers for PCOS patients are the presence of Ulnar loops in middle and little fingers of right and left hand. The buccal micronucleus cytome assay in exfoliated buccal cells, we found decrease in frequency of micronuclei and significant increases in frequency of karyolysed nuclei in polycystic ovarian syndrome patients. Chromosome aberration analysis revealed a significant increase in frequency of chromosome aberrations (CAs) in PCOS patients when compared with controls. Conclusions: From this present work it can be concluded that non-invasive technique like dermatoglypics analysis and buccal micronucleus cytome assays with exfoliated buccal cell can also be effective biomarkers for PCOS, along with increased CAs in lymphocytes as a sign of genetic instability. There is a hypothesis that micronuclei and chromosomal aberrations could have a predictive value for cancer. From this present work it can be concluded to some extent that non-invasive technique like dermatoglypics and buccal cell analysis can also be effective for diagnosis.

진도의 육상에 서식하는 하모섬모충류 2종, 근사전열하모충 (Holostichides chardezi Foissner, 1987)과 팔핵경피하모충[Rigidocortex octonucleatus(Foissner, 1988)]은 한국에서 처음으로 발견된 종으로서 이들에 대해서 자세히 재 기재하고 이들의 형태적 변이에 대해서 고찰하였다. 이 두 종의 식별형질에 대해서 요약하면 다음과 같다. 근사전열하모충은 길쭉한 몸을 가지며 뒤틀리거나 유연하다. 표층에는 연노랑의 알갱이 고루 분포하고, 막판구대는 체장의약 $28\%$를 차지한다. 좌우의 중앙복극모열이 쌍으로 존재하며 좌측열은 구부정점까지 이르고, 우측열은 몸의 중앙까지 이른다. 후방극모가 없고, 좌우 측극모열은 몸의 후단까지 이르지만 서로 연결되지 않는다. 28-42개의 대핵과 1-5개의 소핵은 몸 전체에 흩어져 있다. 미극모는 3개, 등쪽섬모열은 4열이다. 팔핵경피하모충은 계란형의 몸을 가지며 뻣뻣하거나 잘 수축하지 않는다. 연노랑의 세포질 결정체와 지방체가 촘촘히 존재한다. 막판구대는 체장의 약 $40\%$를 차지한다. 후방극모는 5개이고. 좌우 측극모열은 몸의 후단까지 이르지만 서로 연결되지 않는다. 8개의 대핵이 몸의 중앙에 세로로 배열한다. 미극모는 3개, 등쪽섬모열은 분절된 것이 많으며 7-10열이다.
