[Small bowel metastasis from breast cancer: a case report].

Breast cancer is a common malignancy in women and frequently metastasizes to various organs such as liver, lung, brain, bone and so on. But metastasis to gastrointestinal tract is rare. We describe a 73-year-old woman with small intestinal metastasis of breast cancer.

[A case of metastatic hepatocellular carcinoma of the ovary].

Although advances in imaging technology have allowed for earlier detection of disease, hepatocellular carcinoma is usually asymptomatic and discovered at an advanced stage with metastasis. The most common sites of metastasis include lung, peritoneum, adrenal gland, and bone, but rarely, the nasal cavity, orbit, gallbladder, and ovary can be metastatic sites. We experienced a case of metastatic hepatocellular carcinoma of the ovary in a living patient.

Protective effects of epicatechin against the toxic effects of streptozotocin on rat pancreatic islets: in vivo and in vitro.

Introduction: Green tea catechins have diverse pharmacological effects such as anticarcinogenic and antioxidant activities.

Aim: To study the protective effects of green tea (-)-epicatechin (EC) against the toxic effects of streptozotocin (STZ), a selective beta cell toxin, on pancreatic islets in vivo and in vitro.

Methodology: Rats were randomly divided into four groups: control, EC (30 mg/kg)-treated, STZ (60 mg/kg)-treated, and EC plus STZ (same doses; EC+STZ)-treated rats.
