The objective of the present investigation was to evaluate the therapeutic efficacy of Silymarin in DOCA salt induced hypertension in unilateral nephrectomized rats. Unilateral nephrectomy was performed in female Wistar rats (150-200 g). A week after unilateral nephrectomy, hypertension was induced by DOCA (25 mg/kg, once a week; s.c; for 4 weeks) dispersed in cottonseed oil. The effect of Silymarin (300 mg/kg and 500 mg/kg, p. o., for 4 weeks) was evaluated in DOCA salt induced hypertensive rats. Systolic blood pressure (BP) was measured once every week during the treatment schedule. After completion of treatment schedule, heart rate, arterial blood pressure and vascular reactivity to various drugs were recorded. Rats from individual group were sacrificed, the heart was dissected out and antioxidant enzyme level SOD, CAT, GSH and TBARS were measured. Urine excretions were measured by flame photometer. Silymarin (300, 500 mg/kg/day, p.o.) significantly ($p$ <0.05) reduced systolic blood pressure, heart rate, basal arterial blood pressure and pressor responses to NA, Adr, PE and 5-HT in animals treated with DOCA salt as compared with DOCA-salt hypertensive rats. Silymarin significantly increased antioxidant enzyme level of SOD, CAT, GSH, urinary $Na^+$ excretion and decreased TBARS level, urinary $K^+$ excretion compared with DOCA hypertensive group. Silymarin exhibits significant antihypertensive activity in DOCA salt model of hypertension.

Chronic osteitic rhinosinusitis as a manifestation of cystic fibrosis: A case report

Jadhav, Aniket B.,Lurie, Alan G.,Tadinada, Aditya Korean Academy of Oral and Maxillofacial Radiology 2014 Imaging Science in Dentistry Vol.44 No.3

A 28-year-old male patient with a history of cystic fibrosis (CF) was referred to the University of Connecticut School of Dental Medicine for an evaluation of a cystic lesion in the right maxilla using cone-beam computed tomography (CBCT). CF is an autosomal recessive disease characterized by an abnormal production of viscous mucus, affecting the mucociliary clearance. The CBCT scan revealed a large cystic lesion in the right maxilla extending from the right maxillary second molar to the midline in the region of the right central incisor with a significant buccal expansion. Further evaluation revealed complete opacification of the paranasal sinuses with medial bulging of the lateral maxillary sinus walls. The maxillary and sphenoid sinuses also appeared hypoplastic. The peculiar finding seen in this case was the presence of marked sclerosis and an increase in the thickness of the adjacent bony framework. This report aimed to describe the common sinonasal findings associated with CF and its underlying pathophysiology.

Clival lesion incidentally discovered on cone-beam computed tomography: A case report and review of the literature

Jadhav, Aniket B.,Tadinada, Aditya,Rengasamy, Kandasamy,Fellows, Douglas,Lurie, Alan G. Korean Academy of Oral and Maxillofacial Radiology 2014 Imaging Science in Dentistry Vol.44 No.2

An osteolytic lesion with a small central area of mineralization and sclerotic borders was discovered incidentally in the clivus on the cone-beam computed tomography (CBCT) of a 27-year-old male patient. This benign appearance indicated a primary differential diagnosis of non-aggressive lesions such as fibro-osseous lesions and arrested pneumatization. Further, on magnetic resonance imaging (MRI), the lesion showed a homogenously low T1 signal intensity with mild internal enhancement after post-gadolinium and a heterogeneous T2 signal intensity. These signal characteristics might be attributed to the fibrous tissues, chondroid matrix, calcific material, or cystic component of the lesion; thus, chondroblastoma and chondromyxoid fibroma were added to the differential diagnosis. Although this report was limited by the lack of final diagnosis and the patient lost to follow-up, the incidental skull base finding would be important for interpreting the entire volume of CBCT by a qualified oral and maxillofacial radiologist.
