Distribusi Dan Kelimpahan Fitoplankton Yang Berpotensi Menyebabkan Habs (Harmful Algal Blooms) Di Muarasungai Banjir Kanal Timur, Semarang

Activities in Banjir Kanal Timur river like industry activities and settlements was expected give contribution to supply nutrient in estuary and can cause blooming of phytoplankton and decrease estuary's water quality. The aimed of this research was to determine spatiotemporal distribution and abundance of potentially phytoplankton which effect Harmful Algal Blooms (HABs) based on tidalrange. This research used case studly method (descriptive) and purposive sampling technique. Samples were takenfrom 4 stationevery four days for three replication.Station (I)in mangrove and fishpond area, station (II) in confluence of two rivers area, station III and IV in the beach with boat's traffic track. Phytoplankton consisted of 4 class and 24 genus, four of them was genus HABs included Skeletonema sp. with abundance (765- 1911 ind/L at high tide, 233- 574 ind/L at low tide), Trichodesmium sp. (785- 1678 ind/L at high tide, 764- 1168 ind/L at low tide), Pseudonitzschia sp. (127- 191 ind/L at high tide, 0- 84 ind/L at low tide) and Ceratium sp. (0- 63 ind/L at high tide, 0-42 ind/L at low tide). Skeletonema sp. (regular distribution patterns) and Trichodesmium sp. (uniform distribution patterns) were dominant in all station at high tide or low tide. Pseudonitzschia sp.(uniform distribution patterns) was in all station at high tide andat low tide was in station II,III and IV. Ceratium sp. (regular distribution patterns) was in station I and IV at high tide, and at low tide was found in station III and IV

Graves’ Dermopathy: Responsive with Intralesion Steroid

A 51-year-old male came with thickening lesion in both legs since 2.5 years before presented. It started with small lesion and went larger. Before diagnosed, he was admitted to hospital due to unresolved headache. He complainted nausea, easily hungry, protrusion of both eyes without diplopia or diminution of vision, tremor, palpitation, and unintentional weight loss (25-30 kgs in a year). On examination, it was found that he was in thyrotoxic condition and has diffuse goiter. From skin examination he had raised hyperkeratotic, and waxy plaque like lesions over both pretibial region. Laboratory examination confirm for thyrotoxic with presumably Graves’ disease with the result on Table 1. Thyroid scintigraphy showed diffused enlargement and increased uptake. Skin biopsy from the pretibial skin showed epidermis with vacuolar degeneration, partly spongiotic and hyperpigmentated, thickening basalis membrane, miksoid dermis and spreading chronic inflammatory cell in perivascular and periadneksal. It confirmed the diagnosis of myxedema hystologically
