Lethbridge Herald (Newspaper) - February 14, 1973, Lethbridge, Alberta
Wednesday, February 14, 1973 - THE LETHBRIDGE HERALD - 39 Paragon of dedication U of L biologist 'keen' on parasites University-of Lethbridge professor Paial Lewis takes his biology seriously. Any mam who willingly ingests pinworm eggs, juf 1 so he can experience first-hand the symptoms of being host to that parasite, must be dedicated to his work. A member of the U of L biological sciences department since 1967, Dr. Lewis specializes in parasitology, the study of parasites and their hosts. He is currently completing a detailed study of a snail parasite with the tongue-twisting njrae "Leucochloridium var-iae." The parasite is a member of a group of flatworms called trematodes, or flukes. Dr. Lewis spends a good deal of his waking hours seeking, growing, dissecting and observing the tiny pulsating parasite which spends its larval stages in land snails and is transferred to birds - mainly wild song-birds - for its adult existence. The work, together with studies on the parasites of land snails in Alberta and the Northwest Territories, has been partially funded by grants from the National Research Council, the Boreal Institute of the University of Alberta, and the U of L Research Committee. "Essentially," says Dr. Lewis, "my students and I have been looking at the phenomenon of growth in these parasites - how and where they grow, whether growth is more successful in one location in the host than another. The findings can be generalized to ether parasites and provide insight into the growth of parasitic and free-living organisms." USE CHICKENS Initially, Dr. Lewis began his studies to discover if the snail parasite could be raised in hatchery chickens - using wild songbirds in hopes of finding some infected with the parasite wasn't a good research technique, and hatchery chicks were clean and uninfected. "Both Co-op and Swifts Hatcheries have been very helpful supplying chicks and fertile eggs," acknowledged Dr. Lewis. At first, he got the chickens to swallow the larval parasites; later he learned the experiments were more efficient if the larvae were introduced through the cloacal vent since the worms inhabit the extremities of the intestinal canal. "I've also been growing the parasite and studying its development in an alternate site, on the membranes which surround the developing chicken embryo," comments Dr. Lewis. "This work is in co-operation with two colleagues, Drs. Bernard Fried and Warren Guy, Lafayette College, Easton, Pennsylvania." Fortunately, Leucochloridium variae - an earnest and colorful little parasite when viewed under the microscope-does not affect human beings. And it is not present in the variety of land snails found in Alberta. "Alberta snails aren't free from infection," Dr. Lewis points out, "they just don't have this particular parasite, so I collect the snails 1,300 miles southeast, in Nebraska, and 1,-200 miles north, in the Northwest Territories." POPULAR FILM One of the direct results of Dr. Lewis' research is that biology students in 20 universities across Canada and the U.S. are able to view a narrated color film showing the growth cycle and behavior of the parasite. Although its title would never qualify for an Academy Award, the film, "The Life Cycle of the Leucochloridium variae Mcintosh, 1932," is used to illustrate the parasite's growth adaptations. Made in 1969 by Dr. Lewis and Harold Tichenor, a graduate of the U of L and former employee in the U of L Media Centre, the film demonstrates the surprisingly colorful larval parasite, which has definite brown, red and gold rings on its "head" end and pulsates in the tentacles of snails unfortunate enough to become infected with it. Dr. Lewis is keen on other kinds of parasites too - "worms" as he familiarly calls them. He manages to 'infect' even the most queasy observer with a bit of his enthusiastic interest in the creepy-crawlies that can work their way through man's innards, with all sorts of unexpected side effects. "Parasites are very common," says the biologist, "most people have them without realizing it." Dr. Lewis won't toss back a cup of pinworm eggs on demand, but he will seat you in front of the microscope so you can share Ms latest acquisition -some eggs from' the type of liver fluke that infects cattle. Or he'll look in the lab refrigerator and produce a jar of chilled liver flukes, the kind that can infest cattle livers - large, ugly reddish brown leaf-like objects. A biologist is nothing without his specimens. "I'm always looking for specimens," says Paul Lewis. "It makes the classes a lot more interesting if you help students study live organisms." And if there's one thing (hat frustrates him, it's U of L professors who keep their infections to themselves. "It makes me furious," he says. "Just the other day one of my colleague's kids had Ascaris, a large intestinal roundworm. I could have recovered those and used them in the lab. And he never even thought to tell me." 4m' Dr. Paul Lewis . . .this unsuspecting chick will 'breed' snail parasites that the U of L scientist uses in his research. Rembrandt 'may hang" at coast VANCOUVER (CP) - A painting believed to be an early work of Rembrandt van Rijn, the 17th-century Dutch master, may become a Vancouver gallery attraction-provided it is recovered safely from a thief. Owner Charles P. Murano, who recently became a Vancouver area resident, says it was stolen Dec. 27 from a Palm Springs, Calif., gallery where it was on a display for sale. The worlc is called St. Philip Baptizing the Eunuch. Three appraisers valued the painting at up to $900,000. It was insured for $750,000. Mr. Murano, a business mam in the oil and gas development field, said lie acquired it for an undisclosed price from a collector as a investment and he had wanted to sell it at first. "But now I'd like it back, don't need the $750,000. I'd like to have the painting hung in a gallery here in B.C. for the people here to enjoy," said Mr. Murano, an American citizen who recently received preliminary approval of his landed immigrant status application. SEEN BY APPRAISERS Three appraisals were made of the painting while it was in a Palm Springs warehouse. The appraisers thought it may be a work entitled Landscape with the Baptism of the Eunuch. Said one appraiser, a Rembrandt authority and member of the Appraisers' Association of America: "I think I spent about 20 minutes in that warehouse. It was incredibly hot in there - about 120 degrees - and the painting was atrociously packed and was deteriorating. I looked at it carefully with a glass and in my opinion it is a Rembrandt. It looks like an early work, probably 1625 to 1635." He said some clumsy attempts had been made to repair the work but despite the damage of age and the inept repair work the painting had convincing signs of the technique and materials Rembrandt used. Palm Springs police and tf� FBI are investigating the theft. Tickets stolen SYDNEY, Australia (Reuter) - The serial numbers of thousands of American Airlines tickets stolen from the company's office here haye been circulated by Interpol, a police spokesman said. He said the tickets were all blank and needed only a stamp from a travel agency or airline to make them valid. TEXACO CANADA LTD.

Boyle's Column By HAL BOYLE NEW YORK (AP) - One of the hardest ordeals of parenthood is facing up to the realization that after a certain age your children use home only as a resting place between .flights that take them farther and farther away. The house seems so silent and empty when they have gone. That is the way my apartment seems now-now that my daughter has driven off for another try at higher education. As a freshman last year, Tracy Ann loved picturesque little Windham College and its lovely hillside setting in old Putney, Vt., but failed to set any scholastic records. So she decided to take a semester off, a decision I acceded to reluctantly only on her promise that she would return to school at the end of that time. It has become com? monplace now for thousands of young students to drop out of college for* a time in order, as so many of them say, "to find myself." DEPENDS ON HER Whether this is a good or bad thing, generally, I can't say. In Tracy's case, I suppose, the answer still depends on whether she goes on now to make college a meaningful part of her life. Certainly, however, she has matured considerably during her semester off. During this period she wangled a job as copy boy. Although she did her work well, she came early to a realization that being a copy boy was hardly a permanent career for a 19-year-old young lady. These six months have been among the happiest of my life to me. During this time Tracy has learned to keep house, cook, and be a pleasure to her father-so much of a pleasure that I have forgiven her the years of helldom she has put me through during her early teendom. "Honey, you're growing up, but you're only growing up to grow away," I told her as she was packing for her return to college. "Yes Daddy," she agreed with the complacency of the young. "But, I guess that's life." "Well, Dear," I told her. "I hope you have found yourself. "I never was lost," she replied. "I always have known who I am, Daddy. But I am still not sure of where I am going. But I think I would like to do something with the English language." FELT SAD That made me feel a bit sad. For I have been trying to do something with the English language for nearly 62 years. So, cheered on by three boyfriends and a gir' friend, Tracy trudged out of the house. "Kiss me, Daddy." We kissed. Tracy bent her head a moment, then the car roared off. She never waved or looked back. Why do people have children anyway? They just grow up and leave you a prisoner of your echoing memories. Bumper crop forecast LONDON (AP) - The International Wheat Council IWC forecasts a bumper 299.5-mil-lion-ton wheat crop for the 1972-73 crop year, only about 19.5 million tons short of the world record set last year. In its annual wheat review, the IWC says the drop is mainly due to crop failure in the Soviet Union, where the harvest is expected to total 80 million tons, 19 million below last year. The IWC describes the large purchases made by the Soviet Union in the early months of the 1972-73 crop year as the ."most dramatic event in the world grain market since the Second World War." The Wheat Council asserts that this shortfall has dominated world wheat trade in the current crop year, leading to a substantial reduction in stocks in the main wheat exporting countries. Wheat production in the seven main exporters - Argentina, Australia, Canada,, the European Common Market, Spain, Sweden and the United States - is forecast as 112.1 million tons only one million tons less than in the year before. �W��T ON SALE AT OUR 326 7th STREET SOUTH AND COLLEGE MALL LOCATIONS Out they go!
