mean age of 49; 228 were over 65 years of age, with a mean age of 75. Two hundred and ninety-three were male and 215 were female. Seventy-two per cent were diagnosed as schizophrenic, the rest having other diagnoses, for example, affective psychosis, senile psychosis, epilepsy or mental deficiency. The average length of hospitalization for the entire group was 21 years with a range of 2 to 52 years.Of those under 65 years of age, 29 per cent went to live with relatives, 33 per cent were sent to boarding homes, 6 per cent were housed in nursing homes and the rest were living with employers, alone or in Salvation Army hostels. In the over 65-year age group, 9 per cent went to live with relatives, 43 per cent were sent to boarding homes, 39 per cent were placed in nursing homes and 9 per cent in other accommodations.Within the five-year follow-up period 127 patients had died -105 were over 65 years of age with a mean age at the time of death of 78 years. All died of natural causes, except two whose deaths were accidental -one in a house fire and the other as a result of asphyxiation. No one had committed suicide. Four patients could not be traced and 34 had moved out of the province.Of the remaining 343 patients who were alive and residing in the province, 55 per cent had remained continuously in the community during the follow-up period, and 45 per cent had one or more admissions to the psychiatric hospital.Of the readmitted patients 74 per cent spent twelve months or less in the hospital. Ninety per cent had four or fewer readmissions. Fifty-four per cent were readmitted within the first twelve months after discharge. 433 discharged, age, with a

In this study, a composite of bioactive glass (BG) and cordierite (BG-cord) was proposed to increase the strength and bioactivity of BG. Both BG and cordierite were separately synthesized with the method of glass melting, then, they were used to fabricate BG-cord with a variation of sintering temperature (600 to 1000 °C). The highest diametral tensile strength (DTS=30.54 MPa) was shown by the BG-cord with sintering temperature at 925 ºC. Bioactivity tests were conducted by soaking in Hank's balanced salt solution (HBSS) for 7, 14, and 21 days. Apatite formation was examined by using a scanning electron microscope. The results showed that the sample showed good bioactivity with regards to the formation of apatite on the samples, confirmed by the detection of carbonate (C-O) and phosphate (P-O) absorption peaks by Fourier transform infrared spectroscopy and crystalline peaks in the X-ray diffraction pattern.
