Cerebral vasospasm remains a serious problem affecting morbidity and mortality in patients with subarachnoid hemorrhage (SAH) during neurosurgery. We aimed to demonstrate the role of the transient receptor potential channel and other channels for Ca2+ in the etiology of cerebral vasospasm using 2-aminoethyl diphenylborinate (2-APB) and the effective dose range of an unstudied pharmacological agent, which can limit vasospasm. ⋯ In experimental SAH in rats, 2-APB treatment increased the BA wall thickness and reduced the BA lumen diameter, inducing significant vascular changes. 2-APB also alleviated cell apoptosis at 24 hours after SAH.

Harvey Cushing's influence on Norman Dott's work on Acromegaly: Pituitary research, treatment modalities and research dissemination c.1900-c.1960.
To review Dr. Harvey Cushing's influence on Mr. Norman Dott's work on acromegaly and other subjects surrounding the pituitary gland such as pituitary research, treatment modalities, and research dissemination. Dott was the first Professor of Neurosurgery in Scotland during 1947 and was considered a pioneer of the understanding and treatment modalities for pituitary disorders such as acromegaly. During 1923, he published an article regarding pituitary physiology that won him the award for the Rockefeller Fellowship Trust, to travel to Boston Massachusetts, giving him the opportunity to train under Cushing's supervision for the years of 1923-1924. However, similarities can be seen between Dott's physiology project that was completed before he ever met Cushing, as well as his treatment suggestions for acromegaly, after he had finished his training under Cushing's supervision. ⋯ Sir Norman Dott was the first Professor of Neurosurgery in Scotland during 1947 and is well known for his pioneering work on intracranial aneurysms. Although less well known for his contribution to pituitary pathologies, we would like to share his contribution in this regard and correlate it with Cushing's influence.
