INTRODUCTION : Young Mulberry leaves and Twigs are a high quality fodder, readily accepted by all classes of stock gives the following table. Composition of Moradabad, White Mulberry leaves as (%) of dry matter (Sanche Z., 2002) Table (1 (Chemical composition of Mulberry leaves in Indian
Mulberry leaves contain n-containing sugars, rutin, quercetin, volatile oil, amino acid, vitamins and microelements, which have so many pharmacological activities such as reducing blood glucose, antihyperlipidemia, hypertensive, bacteriostasis and antivirus. There are plentiful Mulberry leaves in China and there would be a bright developing and studying future of functional foods and it was found that composition of the Mulberry leaves. Chemical contains several vital material and chemical compounds have the same composition chemical to insulin, which works to burn excess sugar in the body Zou and Chen, (2003). Mulberry leaves is one of the traditional Chinese herbs. There are various effective ingredients in Mulberry leaves. They are mineral constituents, vitamins, food fiber, amino acid, plant sterols, flavones, alkaloids, and polysaccharides; and so on Mulberry leaves have such physiological function as lowering blood glucose. Lowering blood pressure, Lowering cholesterol, resisting decrepitude, keeping digestive and excretory system healthy, preventing and resisting cancer, improving the immune ability. The research progress on chemical constituents and physiological functions of Mulberry leaves in recent years both at home and abroad is summarized and the exploitation and utilization of Mulberry leaves in the field of health care are reported in this paper Wang and Lijian, (2005). MATERIALS AND METHODS: 1 Materials:- Mulberry Leaves obtained from the FruitGarden in Damietta. Alloxan obtained from Research Institute of Ophthalmology Medical Analysis Department, Giza, Egypt. Experimental animals, mal albino rats (Sprague- Dawley white) weighing 140±10g were obtained from the Research Institute of Ophthalmology Medical Analysis Department, Giza, Egypt. METHODS: Mulberry leaves were cleaned thoroughly by washing and sensory evaluation. Were the Following items of tea, stuffing pies and vegetable by 10 people. Sensory evaluation has been applied by questionnaire (Watts et al., 1989). Biological Part: Albino rats, Sprague Dawely strain weighting 140± 10 g. Basal diets: The basal diet was prepared according to the following formula as mentioned by AIN, (1993).
Vitamin mixture components: The used vitamin mixture component was that recommended by Campbell (1963). Vitamin mixture components
Mineral mixture components: Salt mixture used was formulated to (Hegested, 1941). Mineral mixture components
Preparation of diabetic rats Diabetic rats: Diabetes was indicted in normal healthy male albino rats by intraperitoneal injection of alloxan 150mg/kg body weight. According to the method described by (Desai and Bhide, 1985) One week after obtained were samples blood the injection of alloxan, fasting to estimate fasting serum glucose. Rats having fast. Serum glucose more than 190mg/dI.were considered diabetics (NDDG, 1994). Experimental design Twenty Sprague Dawley white male albino rats, weighting about140±10 g were used. The animals were obtained from Giza. Rats (n=20 rats) were housed in wire cages under the normal laboratory condition and fed on basal diet for a week as adaptation period. Diet was given in non-scattering feeding cups to avoid loss or Contamination of food, Water was provided to the rats by means of glass tubes projecting through the wire cage from an inverted bottle supported to one side of the cage. The rats were divided into 4 groups each of 5 rats. The groups of rats were as follows:
Biological evaluation: During the experimental period (5weeks) the consumed feed was recorded every day, and body weight recorded weekly. The body weight gain (B.W.G %), food efficiency ratio (F.E.R.) and also organs weight were determined according to Chapman et al., (1959) using the following equations. B W G % =
FER =
a- Organs weight: Heart, liver and kidneys, of the sacrificed rats were carefully removed, washed in saline solution, dried with filter paper and weighted in dependently organs weight as percentage of final body weight were calculated . b-Blood sampling and organs : At the end of the experimental period blood samples were collected after 12 hours fasting from the portal vein; the rats were scarified after being ether anesthetized. Blood samples were received into clean dry centrifuge tubes, and left to clot at room temperature, then centrifuged for 10 minutes at 3000 rpm to separate the serum. Serum was carefully aspirated and transferred into clean curve t tubes and stored frozen at 20Ù’ C for analysis Malhotra, (2003) At the same time, the organs: Heart, liver and kidneys removed, cleaned weighted and stored in formalin solution (10%) for histopathological investigation as the method mentioned by Drury and Wallington, (1980) Biological analysis: a-The level of sugar was measured in the blood of the all rats weekly using a measurement of sugar. b-Determination of serum glucose: The Principle use of glucose determination according to Trinder, (1969). Determination of liver function: 1-Alkaline phosphatase: Enzymatic colori metric determination of alkaline phosphatase was corried out according to Belfieled and Goldberg, (1971). 2-Determination of GPT (ALT): Determination of GPT was carried out according to the method of Tietz, (1976). 3-Determination of (AST): Determination of GPT was carried out according to the method of Henry,(1974) and Yound, (1975). Determination of kidney functions: 1-Creatinine : Principle: Creatinine in alkaline solution reacts with picric to form a colored complex. The amount of the complex formed is directly proportional to the Creatinine concentration according to Larsen, (1972). 2- Uric acid: Principle: The principle use of uric acid determination according to Carawy, (1955) Statistical analysis: Statistical analysis were performed by using computer program, statistical package for social science (SPSS, 1998), and compared with each other using the suitable tests. RESULTS: Sensory evaluation: Table (2) showed mean values for aroma, taste, color, tenderness and Overall acceptability for all food items, results showed That tea and stuffing pies at the highest rats of acceptance, Tea from sample (18.70±0.26, 38.60± 0.42, 8.80±0.20, 8.70±0.21, 19.20±0.24, respectively and stuffing pies from sample (6.20±0.29, 38.10±0.45, 8.40 ±0.30, 8.40 ±0.26, 18.60±0.26, respectively).where the results were as follows for the vegetable(17.60±0.33, 37.40±0.40, 7.70±0.36, 7.50±0.34, 17.70±0.36, respectively)and all food items from Mulberry leaves showed a highly significant(p>0.05).
