Accessory Hepatic Artery Arising from Celiac Trunk: An Incidence in a Thai Cadaver International Journal of Morphology
Chanasong,Rachanee; Putiwat,Phongpitak; Roboon,Jureepon; Sakulsak,Natthiya.
An exhaustive knowledge of the liver vascular patterns as well as possible anatomical variations is significant in the planning and performance of all liver surgical procedures in order for the vascularity not to be disturbed or not causing necrosis of the liver parenchyma postoperatively. The celiac trunk usually provides three branches; left gastric, splenic and common hepatic arteries. The left and right hepatic arteries generally derive from proper hepatic artery which is a branch of common hepatic artery. To study the incidence of celiac trunk ramification, the branching patterns of the celiac trunk of 23 Thai cadavers (17 males, 6 females) were documented during routine dissection by medical students at the Department of Anatomy, Faculty of Medical...

Increasing of Syncytial Knot and Fibrinoid Deposit in High-Cd Accumulated Human Placentas International Journal of Morphology
Phuapittayalert,Laorrat; Norkaew,Thongchai; Supanpaiboon,Wisa; Chuenchoojit,Supaporn; Hipkeao,Wiphawi; Swaddiwudhipong,Witaya; Sakulsak,Natthiya.
A toxic metal, cadmium (Cd), can accumulate in human organs. Placenta is usually used as indicator organ for Cd exposure. Therefore, we aim to investigate the different of placental morphology between the low- and high-Cd accumulated placentas. The samples were collected from 14 pregnant women who resided in low-Cd contaminated (L-Cd group) and high-Cd contaminated (H-Cd group) areas. The concentrations of Cd in blood (B-Cd), urine (U-Cd) and placentas (P-Cd) were measured by ICP-MS and AAS. The morphological appearance of placentas was examined by using routine paraffin section and H & E staining. The results showed that levels of B-Cd, U-Cd and P-Cd were significantly higher in H-Cd group than in L-Cd group (p= 0.001). Moreover, the B-Cd was...

Metallothionein: An Overview on its Metal Homeostatic Regulation in Mammals International Journal of Morphology
Sakulsak,Natthiya.
Metallothionein (MT) is a ubiquitous protein with a low molecular weight of 6-7 kDa weight and it was first identified in the kidney cortex of equines as a cadmium (Cd)-binding protein responsible for the natural accumulation of Cd in the tissue. The mammalian MT contains 61 to 68 amino acid residues, in which 18 to 23 cysteine residues are present. The expression of MT starts by binding of metal transcription factor-1 (MTF-1) to the regulative region of MT gene called metal responsive elements (MREs). The induction of MT through the MREs region can be initiated by several metal ions such as zinc (Zn), copper (Cu) and Cd. However, Zn is the only heavy metal which can reversibly and directly activate the DNA-binding activity of MTF-1. In mammals four types...
