The experiment on lime storage was divided into two sets. In the first experiment, limes were stored at the room temperature (30+-2 degrees centigrade) for 1 month. In general after 1/2 month, the quality of the stored limes was found to be quite good when compared to that of the fresh ones and the average percentage of disease loss was 4.7%. For 1 month storage the quality was fair and the percentage of disease loss increased to 51.1%. It is obvious that limes stored without any treatment and those stored after being washed had the highest percentage of disease loss. Washing did not only lessen disease occurrence but might also lead to an increase in decay incidence due to moisture penetration and accessibility of wounds to pathogens. The second set of experiments on lime storage was done in the cold room for 3 and 1/2 months. After the first two months of storage the fruits were still in good condition and no disease took place. When it came to the 3rd month, the percentage of average disease loss were 8.6% and 27% respectively and the quality of the fruits as well as their freshness was a bit decreased. The efficiency test of 4 formulas of fungicides namely thiophanate methyl (700 ppm) + dichloran (84 ppm), thiophanate methyl (700 ppm) + captan (750 ppm), dichloran (844 ppm) + captan (750 ppm) and dichloran (844 ppm) showed that the use of thiophanate methyl (700 ppm) + dichloran (884 ppm) in room temperature tend to be most effective in controlling lime diseases during short term storage.

Vandevelde, M. | Fatzer, R.
A lysosomal storage disease with accumulation of periodic acid-Schiff- and Sudan black-positive autofluorescent granules in neurons occurred in one 51/2- and one 7-year-old dachshund. Ultrastructurally, the storage material consisted of membranous material arranged in stacks and fingerprint patterns. The disease was defined as ceroid-lipofuscinosis, and resembled a previously reported case in an adult dachshund.

Adobe Acrobat XI Pro was used to OCR the text and also for the merging and conversion to the final presentation PDF-format. | Cell cultures prepared from the spleen and mesenteric lymph nodes of affected kittens were subjected to histochemical and ultrastructural studies. Macrophages in the cultures contained lipid in the cytoplasm and the ultrastructural studies revealed lysosomes containing lamellae similar in appearance to phospholipids.

Seed produced on diseased plants may carry fungi, bacteria, viruses or combinations of these. Seeds which are disease-free at harvest may become contaminated in poor storage conditions. Infected seed may have reduced viability and longevity, and produce plants with root rots, seedling and leaf blights, stalk rots, ergots, or head moulds. These various conditions may cause death, general unthriftiness of the plant and, therefore, reduced yields. Infection of grain by toxin-producing pathogens may render the produce worthless under some storage conditions. There are numerous prophylactic methods which seedsmen can use to control or prevent seed transmission of diseases and subsequent losses. Management practices such as planting of disease-free seed, crop rotation, time and depth of sowing, control of alternate hosts, and time of harvest may be used to reduce transmission of seed-borne diseases. Curative measures include seed dressings and thermotherapy. The most effective method of prevention of loss is host plant resistance. Fortunately, there are sources of resistance to the major seed transmitted diseases of corn and sorghum. The prevention of disease in stored grains may be achieved by maintaining the correct levels of hygiene, moisture content, relative humidity and temperature during storage.

The fungicidal and waxing methods were used in controlling post harvest diseases and losses in tangerines. The following were observed: 1. Low temperature could inhibit microbial growth and metabolism in fruits, thus fruits had a longer storage life; 2. There were no significant differences sensory evaluation and chemical composition of fruits placed in a cold storage; 3. Fruits treated with benomyl waxed had higher acidity and pH than control; 4. Waxed fruits except benomyl waxed fruits, had significant difference on sensory evaluation from control when stored in ambient temperature; 5. Benomyl and thiabendazol were effective in controlling blue mold, green mold and black mold but less effective in controlling Colletotrichum gloeosporioides; 6. The longer the storage period was, the poorer was the quality of fruits found in both storage conditions; 7. Reduction of weight loss could be achieved by waxing; 8. Post harvest disease caused by Colletotrichum gloeosporioides was found mostly during storage either in low or ambient temperature. Phomopsis sp., Fusarium sp. were also found.
