A small earthenware statuette was evacuated from the votive-depot of acropolis of Gortys, an ancient town in South-Crete/Greece. This ex-voto is dated approximately 7th to 6th century BC and very probably represents some symptoms of a stroke, especially the left facial palsy and the contracture of the left arm. Since the Minoan time until today, people of Crete have been offering ex-votos to gods or saints to ask for help in specific diseases.
Growth activity of the rat septal cartilage was evaluated by incorporating radiolabeled sulfate into three areas of the septal cartilage (anterior, central, and posterior). Growth activity of the septal cartilage was determined in normal rats and in hypophysectomized rats treated either with saline or human growth hormone (hGh) injections. Human growth hormone treatment selectively stimulated sulfate incorporation in the posterior area, which is situated anterior to the septoethmoidal junction, whereas sulfate incorporation was not influenced in the anterior and central area by hGh treatment compared to saline treatment. However, both wet and dry weight was significantly increased by hGh treatment compared to saline treatment in hypophysectomized rats.
The purpose of the present study was to ascertain whether artificial skull deformation, carried out during infancy, has an effect on the pneumatization of the frontal and maxillary sinuses and on the osseous structure of the frontal bone. Thus, two normal and 12 artificially deformed adult human skulls (12 males, two females) from the collection of pre-Columbian Peruvian skeletons and mummies in the Institute of Anthropology and Human Genetics (University of Munich) were investigated by computed tomography. These skulls had been excavated from four sites on the Peruvian coast: Las Trancas, Cahuachi. Pacatnamu, and Estaqueria. The volumes of the maxillary sinuses varied from 5.18 mL to 17.19 mL. Those of the frontal sinuses varied from zero to 6.21 mL. The artificial deformation of the skull, which occurred during infancy, had no influence on the size of the maxillary and frontal sinuses. There was also no difference in the average bone thickness of the os frontale; however, artificial deformation in infancy had an influence on the bone structure, resulting in a tremendous rarefication of the diploe of the frontal bones. Based on these findings we conclude that the various types of skull deformation instituted in infancy seem to exert no inhibitory effect on the pneumatization of either the frontal or maxillary sinuses.
