The other day I watched Dr. Lloyd Banbury hop into his mobile laboratory, sit down at a bench and begin peering through a micro- scope. He was searching for embryo cattle cells one one hundreth off a cubic inch in size. - He and his partner, Sue Hutchins, had just flushed a prize pregnant cow on Browndale Farms, near Paris, Ontario. The pair operate what they call BHL Embryo Transplants. Over the past seven years, they've done close to 4,000 trans- plants. They work out of Paris but six months of the year, travel in Europe and Asia taking their entire equipment in a couple of suitcases! That's because they do non-surgical trans- plants. Banbury was the first Canadian to do this type of artificial insemination. Only superior cattle are given transplants. I joined Lloyd and Sue as they drove their van to another farm in the area. They had already selected the cows that were to receive the embryo. It's the simplest procedure you can imagine. Embryo cattle transplants I had seen in the past involved surgery, and were done in clinical surroundings. But in this case, Sue just lifted up the cow's tail, Dr. Banbury in- serted a tube and the embryo released. The cow remained in her stall and even kept on chewing her cud while the whole thing was going on. An average of seven cows receive embryo from a. single surrogate cow. Some cows have produced 30 em- bryo transplanted calves over two or three years, in- stead of two or three by normal birth. Since it's not unusual for a prize cow to be in the quarter million dollar bracket, you've got quite a profitable venture. So' occasionally, it appears, it pays to mess around with Mother Nature. Toothbrush benefit to handicapped A new toothbrush, which could revolutionize the brushing habits and improve the dental hygiene of mil- lions, has recently become available on the Canadian market. It was invented by a practising dentist of 28 years, Dr. George Collis, to make the daily chore of brushing one's teeth a simpler, safer, more effec- tive and less time-consuming task. What makes this brush dif- ferent is its curved bristles. Originally designed to en- able mentally or physically handicapped people to brush more easily and effectively, it has apparently accom- plished that objective and it has also proven its merits among the general public as well. Dr. Collis maintains that the two techniques most de- plored by dentists, namely the horizontal and the scrub method, are those most widely used by the public and that it was not the tech- nique that was at fault, it was the instrument. He also claims that automatic tooth- brushes only compound the problem of injury to the gin- gival (g'um) tissues. By simply scrubbing indis- criminately for 30 seconds, instead of the 3 to 5 minutes necessary with a conven- tional toothbrush, plaque is controlled, the teeth are cleaned, and the gums are massaged, with the curved bristle. This makes the brush excellent for children, who are often impatient to com- plete the chore, very popular in institutions where a pati- ent has difficulty or requires a second party to clean his teeth, and likely to gain rapid acceptance by the general public decause of its speed and simplicity. After clinical testing for a year, the curved bristle toothbrush has shown that it improve dental hygiene..----- Institutions and nursing care centres may also re- ceive, free of charge, a 44 - page in-depth and highly -de- tailed summary of case stu- dies done with various handicapped groups.
