Intravascular "mulberry-like" bodies: morphological, immunohistochemical, and ultrastructural observations of an incidental finding caused by autolysis?
Intravascular "mulberry-like" bodies in a stillborn female infant with moderate maceration are reported. The histogenesis of these structures is discussed based on light-microscopic, immunohistochemical and ultrastructural findings. No demonstrable causal relation between the intravascular lesions and fetal death was found, the cause of death being attributed to intrauterine asphyxia. It is concluded, that intravascular "mulberry-bodies" most likely represent artifacts due to red blood cell autolysis.

[Fluoride accumulation and distribution in mulberry insects near fluoride pollution sources].
Fluoride accumulation and the relative fluoride loading of different body parts in wild mulberry silkworm (Bombyx mandarina M.), mulberry geometrid (Pathonandria atrineata B.), and mulberry silkworm (Bombyx mori L.) near fluoride pollution sources were studied. Comparison of the fluoride content of insect bodies and mulberry leaves showed that insects collected from polluted sites had increased fluoride accumulation. The digestive tract of the insect had much higher fluoride content than the other parts of the body and was considered to be the important organ of fluoride accumulation. There were also wide differences in fluoride accumulation between different insect species within the same polluted site. The highly significantly correlation between fluoride contents of wild mulberry silkworm, mulberry geometrid, and mulberry silkworm with that of the mulberry leaves on which they were collected was found.

[Separation and properties of multiple forms of acid phosphatase from the tissues and organs of the mulberry silkworm].
The multiple forms of acid phosphatase from the hemolymph, fat body, intestinal wall and silk gland of the silkworm larvae differing in their mobility during polyacrylamide gel electrophoresis were separated by isoelectrofocusing, gel filtration and ion-exchange chromatography and characterized in terms of their molecular weight, isoelectric points and substrate specificity. It was found that silkworm tissues contain several enzyme forms possessing broad substrate specificity (EC 3.1.3.2) as well as forms predominantly catalyzing the hydrolysis of glucose-1-phosphate (EC 3.1.3.10). The enzyme forms with a broad substrate specificity were detected in all tissues studied with the exception of hemolymph and were found to have the molecular weights above 60,000, pI greater than pH 6.0 and the highest activity within the pH range of 3.0-4.5. The enzyme forms causing predominant hydrolysis of glucose-1-phosphate detected in the hemolymph, fat body and intestinal wall are characterized by Mr = 30,000-100,000, pI below 6.0 and the highest activity within the pH range of 4.8-5.6. A possible role of the multiple forms of acid phosphatase in silkworm metabolism is discussed.

Effects of mulberry leaves to replace rapeseed meal on performance of sheep feeding on ammoniated rice straw diet.
This study was conducted to investigate effects of leaves of mulberry tree (Morus alba) as a protein supplement to isonitrogenously replace rapeseed meal (RSM) on performance of growing lambs offered ammoniated rice straw (ABRS) (Trial 1), and to evaluate the digestive characteristics of the ABRS supplemented with different ratios of RSM and mulberry leaves in terms of in vitro gas production (Trial 2). In Trial 1, 45 Huzhou lambs were divided into five equal groups according to their body weight and gender. Lambs in each group were kept in three pens (male, female and mixed (one male and two females)), and received one of the following dietary treatments: 100g RSM (A), 75g RSM plus 60g mulberry leaves (B), 50g RSM plus 120g mulberry leaves (C), 25g RSM plus 180g mulberry leaves (D), and 240g mulberry leaves (E). All animals were given ABRS ad libitum along with 100g ground corn per head per day. The intake of ABRS was slightly increased with the supplementary level of mulberry leaves, and hence total intake increased with the increasing level of mulberry leaves. The growth rates were higher in diets A and E than those in other treatments (P<0.05), with little difference between diets A and E, and the slowest in C. Animals of all genders showed a similar trend, though male lambs was higher in weight gain than the female. While feed efficiency was higher in diet A, concentrate consumption per kilogram of weight gain was lower when higher level of mulberry leaves was supplemented (diets D and E). Feed cost per kilogram gain was lower in diets E and A compared to other treatments. Degradation of dry matter in the rumen of sheep were higher for mulberry leaves than for RSM, but crude protein was less degraded for mulberry leaves than for RSM. The potential GP was significantly higher in diet A than those in B, C and D (P<0.05), and higher in E than in C (P<0.05) (Trial 2), indicating a negative associate effect of mulberry leaves and RSM on digestion. It is inferred that mulberry leaves may be used as a protein supplement to ammoniated straw diets to fully substitute for RSM, but these two supplements should unlikely be supplemented together to avoid the negative associate effect.

[Ninety-day dietary toxicity study of mulberry leaf extract in rats].
Mulberry leaf extract was studied toxicologically in male and female SD rats. The extract was administered orally at concentrations of 0% (control group), 0.1%, 0.4% and 1% in basal diet for 90 days. No remarkable change in test animals of both sexes was observed in terms of body weight gain or at necropsy. Hematology and blood chemistry revealed no abnormalities. Pathological examination revealed no toxic change in any organ observed. These findings indicate that dietary intake of 1% mulberry leaf extract for 90 days (884.5 mg/kg/day for males and 995.7 mg/kg/day for females as mean daily intake) causes no toxicological change in rats.

The ultrastructural study in a case of Fabry disease.
An investigation of the ultrastructural study was conducted on specimens from a typical patient with Fabry disease. Numerous characteristic cytoplasmic inclusions were observed in the vascular endothelial cell, pericyte, smooth muscle cell, nerve and eccrine sweat glands, the lamellar pattern of which were considerably variable in various types of gland cells. Large vacuolar inclusions predominated in clear cells of the secretory coil; lesser vacuoles were also seen in the coiled duct, and the basal cells of the straight duct toward the coiled duct displayed mulberry-like figures. There were some clear cells showing cell damage and necrosis in the secretory coil. Lamellated bodies were noted in the axons and schwann cells around the eccrine sweat glands. The small blood vessels around the eccrine glands were narrowed by swollen endothelial cells with heavy inclusions. These intracytoplasmic deposits may be responsible for the decreased sweating ability in Fabry disease. The factors related to hypohidrosis are also discussed.

A combined scanning and transmission electron microscopic study and electron probe microanalysis of human pineal acervuli.
Untreated, decalcified and trypsinized acervuli from human pineal bodies were studied with the scanning and transmission electron microscope as well as by electron probe microanalysis. The mulberry-like acervuli are composed of a various number of spherical lobes (135-800 mum) between which clustered groups of globuli (4--14 mum in diameter) are observed. The acervular lobes are very probably formed by an aggregation of these globuli. Small round particles 125--500 A in diameter are observed on the surface of the pineal concretions. These are not influenced by either decalcification or trypsin treatment. The acervular mineral corresponds morphologically to hydroxyapatite. The electron probe microanalysis reveals the existence of calcium and phosphorus as main components of the acervuli. Small quantities of magnesium and strontium were also detected.

Mulberry extract supplements ameliorate the inflammation-related hematological parameters in carrageenan-induced arthritic rats.
Mulberry fruit (Morus Lhou Koidz.), a rich source of the major anthocyanin, cyanidin 3-glucoside (C3G), has traditionally been used for the treatment of inflammatory conditions including rheumatic arthritis. In this study, we evaluated the efficacy of orally administrated methanolic mulberry fruit extract (ME) in carrageenan-induced arthritic rats, based on previously observed in vitro antioxidant and anti-inflammatory activities. A significant attenuation of hind paw inflammation characterized by fluid accumulation, uric acid production, and rheumatoid factors induced by carrageenan was observed following the intake of both ME (50 mg/kg of body weight) and C3G (10 mg/kg of body weight). Moreover, alterations in hematological parameters such as serum triglyceride, high-density lipoprotein-cholesterol, and atherogenic index following carrageenan administration were partially reversed by the administration of ME. It is concluded that dietary mulberry fruit extracts elicited protection against carrageenan-induced inflammation.

Antioxidant role of mulberry (Morus indica L. cv. Anantha) leaves in streptozotocin-diabetic rats.
BACKGROUND: The antihyperglycemic and antioxidant role of mulberry (Morus indica L.) leaves were investigated. METHODS: Streptozotocin (STZ)-induced diabetic male Wistar rats were used as experimental models; one group was given 25% dry mulberry leaf powder mixed with the standard diet and another group was given standard diet for a period of 8 weeks. The antihyperglycemic and antioxidant role of mulberry was assessed by determining its effect on blood glucose, lipid peroxidation, reduced glutathione (GSH) concentrations and on the activity of glucose-6-phosphate dehydrogenase (G6PDH) and various antioxidant enzymes in erythrocytes and compared with that of controls. RESULTS: Mulberry-treated diabetic rats showed a significant decrease in fasting blood glucose concentrations indicating a good glycemic control. Increased lipid peroxidation and the activity of catalase (CAT) in erythrocytes observed in diabetic controls were significantly decreased by mulberry leaves (48% and 33%, respectively). Decreased GSH concentrations and the activity of glucose-6-phosphate dehydrogenase and antioxidant enzymes viz., glutathione peroxidase (GPx), glutathione reductase (GR), glutathione-S-transferase (GST) and superoxide dismutase (SOD) observed in uncontrolled diabetes were improved (52%, 69%, 151%, 95%, 24% and 106%) by mulberry treatment very efficiently. CONCLUSION: Mulberry leaves possess antihyperglycemic and antioxidant properties.

Pharmacological studies on root bark of mulberry tree (Morus alba L.)
Pharmacological studies were done on the root bark of mulberry tree and pharmacological effects were compared with the clinical effects of "Sohakuhi" in Chinese medicine. n-Butanol- and water-soluble fractions of mulberry root had similar effects except for those on the cadiovascular system. Both fractions showed cathartic, analgesic, diuretic, antitussive, antiedema, sedative, anticonvulsant, and hypotensive actions in mice, rats, guinea pigs and dogs. There appears to be a correlation between the experimental pharmacological results and the clinical applications of mulberry root found in the literature on Chinese medicine.

Resveratrol-associated renal toxicity.
Resveratrol, (3,5,4'-trihydoxystilbene) a compound found in grapes, mulberries, and peanuts, has antimycotic, antiviral, and beneficial cardiovascular and cancer preventive activities. It is being developed for several clinical indications. To evaluate the potential toxicity of resveratrol, rats were administered by gavage 0, 300, 1000, and 3000 mg trans-resveratrol per kilogram body weight per day for 4 weeks. Most of the adverse events occurred in the rats administered 3000 mg per kilogram body weight per day. These included increased clinical signs of toxicity; reduced final body weights and food consumption; elevated BUN, creatinine, alkaline phosphatase, alanine aminotransferase, total bilirubin, and albumin; reduced hemoglobin, hematocrit, and red cell counts; and increased white cell counts. Increases in kidney weights and clinically significant renal lesions, including an increased incidence and severity of nephropathy, were observed. Diffuse epithelial hyperplasia in the bladder was considered, equivocal and of limited biological significance. No histological effects on the liver were observed, despite the clinical chemistry changes and increased liver weights in the females. Effects seen in the group administered 1000 mg resveratrol per kilogram body weight per day included reduced body weight gain (females only) and elevated white blood cell count (males only). Plasma resveratrol concentrations in blood collected 1 h after dose administration during week 4 were dose related but were relatively low given the high dosage levels; conjugates were not measured. Under the conditions of this study, the no observed adverse effect level was 300 mg resveratrol per kilogram body weight per day in rats.

Response to oxidative stress as a welfare parameter in swine.
In pigs, the genetic selection for lean, large muscle blocks and fast growth has been linked to an increased prevalence of metabolic diseases such as porcine stress syndrome and mulberry heart disease. These diseases are associated with cardiovascular inadequacy, which may lead to oxidative stress. In the present study, reactive oxygen metabolites (ROMs) and the anti-oxidant power (OXY) in sera of different swine groups were investigated. The following groups were selected (each around 80 kg body weight): wild boars (WB), Cinta Senese (CS), and Landrace x Large White (LxLW), the latter as both specific pathogen-free (SPF) and intensively farmed animals. In addition, a group of LxLW agonic sows (AS) was also investigated; this group is known to be under oxidative stress. Two colorimetric micro-methods were used to measure ROMs and OXY; ROMs were expressed as mM H(2)O(2) and OXY as microM HOCl neutralised. Between groups, average ROM and OXY values were found to be significantly different by one-way ANOVA (P < 0.001). ROM levels were lower in WB (13.41 +/- 1.85) and CS (19.27 +/- 1.68), and highest in LxLW (42.00 +/- 1.36). OXY values ranged from 260.10 +/- 22.13 (WB) to 396.90 +/- 9.83 (LxLW). Only one swine group (the CS group) showed a significant, positive correlation between ROM and OXY values. The AS group even showed a negative correlation between ROM and OXY values. These results imply satisfactory environmental coping occurred only within the CS group. Results are discussed in the light of animal welfare legislation, food safety and consumers' protection.

Traceability of inbred and crossbred Cinta Senese pigs by evaluating the oxidative stress.
Previous studies on the oxidative stress in swine indicated a strong link between the values of reactive oxygen metabolites (ROMs), the subsequent antioxidant adaptive response (OXY) and the genetic selection. Such findings, mainly related to a cardiovascular inadequacy in lean, large muscle blocks and fast growing breeds, is associated with specific metabolic diseases such as porcine stress syndrome and mulberry heart disease. In this study, we investigated the oxidative stress parameters to trace the genetics of Cinta Senese (CS) pigs, a historical breed free-range reared in Siena countryside. Sera from CS (n = 24) and Large White x CS (LW x CS) (n = 24) groups around 120 kg body weight fed the same diet were sampled at slaughter. Sera from wild boars (WB) (n = 24) hunted in the same district were also considered. ROMs and OXY were evaluated in the three groups of swine. Significant differences by one-way anova (P < 0.05) between groups were found for both procedures. ROM levels were lower in WB (9.79 +/- 5.76 mm H2O2) and CS (18.02 +/- 7.42 mm H2O2), and highest in LW x CS (42.78 +/- 8.61 mm H2O2). OXY values ranged from 271.37 +/- 50.90 microm neutralized HOCl (WB) to 343.21 +/- 57.45 microm neutralized HOCl (LW x CS). Results indicated that the evaluation of the oxidative stress can effectively trace the CS pigs, thus aiding in preserving the overall specific traits of such a historical animal.

Role of specific activators of intestinal amino acid transport in Bombyx mori larval growth and nutrition.
Nutrient absorption and its modulation are critical for animal growth. In this paper, we demonstrate that leucine methyl ester (Leu-OMe) can greatly increase the activity of the transport system responsible for the absorption of most essential amino acids in the larval midgut of the silkworm Bombyx mori. We investigated leucine uptake activation by Leu-OMe in brush border membrane vesicles and in the apical membrane of epithelial cells in the midgut incubated in vitro. Moreover, the addition of this strong activator of amino acid absorption to diet significantly affected larval growth. Silkworms fed on artificial diet supplemented with Leu-OMe reached maximum body weight 12-18 h before control larvae, and produced cocoon shells up to 20% heavier than those of controls. The activation of amino acid absorption plays an essential role in larval development so that larval growth and cocoon production similar to controls reared on an artificial diet with 25% of dry mulberry leaf powder were observed in silkworms fed on an artificial diet with only 5% of mulberry powder.

Production of silkworms with conjugated linoleic acid (CLA) incorporated into their lipids by dietary CLA.
Silkworms with conjugated linoleic acid (CLA) incorporated into their lipids (designated CLA silkworms) were produced to enhance the quality of silkworms having a synergistic effect with CLA functions by dietary synthetic CLA. Silkworm larvae were fed fresh mulberry leaves (control diet) until the third instar stage and were then subjected to various levels (0%, 0.1%, 1%, 5%, and 10%) of CLA-sprayed mulberry leaves (designated CLA diet) beginning on the first day of the fourth instar stage and continuing to the third day of the fifth instar stage. CLA contents in CLA silkworms increased proportionally with increasing CLA levels of CLA diets. CLA silkworms on a 1% CLA diet contained 2.2 g CLA/100 g lipid without body weight reduction, whereas CLA silkworms on a 10% CLA diet contained 14.8 g CLA/100 g lipid with a significant reduction of body weight, relative to the control silkworms. The CLA content in the lipids of CLA silkworms on a 10% CLA diet was significantly higher than that of CLA silkworms on a 5% CLA diet. A 0.1% CLA diet was not sufficient to accumulate CLA in the silkworms. Most of the CLA (approximately 99%) of silkworm lipids was present in triglyceride (TG) with a similar ratio of c9,t11 and t10,c12 CLA isomers. These results suggest that a 1% CLA diet was suitable for the production of CLA silkworms.

Entomopoxvirus of cotton bollworm, Helicoverpa armigera (Hbn.).
Occurrence of an Entomopoxvirus (EPV) from a lepidopteran insect viz;. cotton bollworm, H. armigera (HaEPV) along with gross pathological symptoms is reported for the first time in India. Histopathological study revealed that the fat body being the most favoured site of infection followed by haemocytes and gut epithelium. HaEPV was found to be not cross infective to six of the agricultural lepidopteran insect pests except for the potato black cutworm, Agrotis segetum registering 100% mortality showing typical symptom. Further, safety of HaEPV was shown against beneficial insect like mulberry silkworm, Bombyx mori and an useful insect general predator, Chrysoperla carnea.
