역세척 후 응집제를 여과사에 주입한 수 여과를 실시한 결과 초기에 높게 나타났던 탁도의 거의 제거되는 것을 알 수 있었으며 pH의 변화에 따른 초기의 탁도 변화는 pH5와 pH7에서 보다 낮은 탁도의 수질을 얻을 수 있었다. pH5부근에서 알루미늄의 존재형태가 $Al(OH)^{2+},\;Al(OH)_2^+$로 많이 존재하며, pH7에서는 $Al(OH)_3$으로 존재하여 모래 표현의 (-) 전하를 감소시킬 수 있는 결과로 판단되었다.

The lanral characters of Petrolisthes japonicus (De Haan, 1849), Porcellanidae, were described and illustrated. The lanral development of P. juponicus includes the two zoeal and one megalopal stases. The first and second zoeal stases lasted about 4 and 10 days, respectively. It took about 14 days to attain megalopa from hatching-The larval characteristics of P. japonicus were compared with those of other knouts species of Petrolisthes. Consequently, the lanrae of P. japonicus are more closely related to P elongatus and P ornutus than other Petrolisthes species, but the present species can be distinguished from these Petrolisthes species by morphological characteristics.

Background: Oral lichen planus (OLP) is categorized as premalignant lesion although its malignant potential is a matter of controversy. The objective of this study was to investigate Ki67 expression in OLP, oral epithelial dysplasia and oral squamous cell carcinoma (OSCC). Materials and Methods: Expression of Ki67 was evaluated through immunohistochemistry (IHC) in groups of A (17 cases of epithelial hyperplasia), B (16 cases of OLP), C1 (10 cases of mild epithelial dysplasia), C2 (10 cases of severe epithelial dysplasia), D1 (10 cases of well-differentiated OSCC), and D2 (10 cases of poorly-differentiated OSCC). Results: There was a significant difference in Ki67 expression based on quantitative analysis among the six studied groups as well as group B compared bilaterally with groups C2, D1 and D2 (p< 0.0001). However, there was no significant difference between groups B and C1 or between groups D1 and D2 (p> 0.05). Conclusions: Based on the results of the present study it may not be possible to definitely consider malignant transformation potential for OLP. However, expression of Ki67 was significantly higher in OLP than that of epithelial hyperplasia with no significant difference from that of mild epithelial dysplasia. This should be considered by clinicians to carefully and regularly follow up OLP lesions to detect potential subtle changes at an early stage.

Objective: To investigate the association between CD105 and tumor cell proliferation in salivary gland tumors. Methods: In this study, 59 samples of salivary tumors from Khalili Hospital archive, including 20 cases of pleomorphic adenoma (PA), 20 cases of mucoepidermoid carcinoma (MEC) and 19 cases of adenoid cystic carcinoma, as well as 10 cases of normal salivary gland tissue, were reviewed by immunohistochemistry (IHC) for CD105 and Ki67 staining. Results: CD105 positive vessels were absent in normal salivary gland tissue in the vicinity of tumors (51.6% of all tumors were positive). There was a statistically significant difference in frequency of CD105 staining between PA and malignant tumors and between four groups of different lesions (p<0.000) being highest in MEC. Intratumoral microvessel density was also elevated in malignant neoplasms ($2.61{\pm}3.1$) as compared to PA ($0.46{\pm}0.6$). Normal salivary glands did not express Ki67. There was a statistically significant difference in frequency and percentage of Ki67 immunoreactivity in malignant neoplasms (86.5% and $10.7{\pm}10.8$ respectively) compared to PA (50% and $0.78{\pm}0.2$) and among the four groups values were highest in MEC (p<0.000). Conclusion: n this study, it was observed a higher rate of angiogenesis and cellular proliferation was noted in malignant tumors compared to benign tumors, but no correlation was observed between these two markers.
