In order to evaluate biological effects of Austrian and Italian talc, pulmonary and hemolytic tests as well as pathomorphological examinations were performed. 120 Wistar rats divided into 5 groups were given intratracheally 50 mg of the examined talc dust suspended in 0.5 ml of 0.9 NaCl. The control group received one 0.5 ml dose of NaCl. The observation periods were 6 and 9 months. Then the biochemical tests for hydroxyproline content in the lung were carried out along with patho-morphologic tests to evaluate the fibrogenic activity of the talcs examined. In animals the intratracheal insufflation of talc dust causes inflammatory changes within the bronchi and lungs. On the basis of biochemical examination of lung homogenates, the differences in the hydroxyproline content were determined. After 6 months the symptoms of chronic inflammation and cellular modules developed. Within another 3 months the symptoms of chronic atrophic inflammation in the bronchi were observed and cellular modules containing dust particles were detected in the lung. Hemolytic test revealed a slightly higher degree of aggressiveness of the Austrian talc.
Rats: Night of Terror (Italian: Rats - Notte di terrore) is a 1984 post-apocalyptic horror film directed by Bruno Mattei and Claudio Fragasso about a biker-gang that find themselves trapped in an abandoned research lab fighting for their lives against hordes of bloodthirsty killer rats.[3]
Set 225 years after a nuclear holocaust in 2015 in the modern day, the survivors are divided between those who live in comfortable underground cities and the "New Primitives" who live in the sunlight. A group of 11 of these people come across a mysterious, abandoned village. Despite the presence of numerous horribly mutilated corpses, the adventurers decide to settle in town after discovering a large amount of food, a greenhouse with various fruit trees and a reservoir of drinking water. The following night hundreds and hundreds of hungry genetically mutated rats are ready to attack them one by one.[2]
Tarus is the next killed as the survivors attempt to escape the basement, as he falls down the stairs and is devoured. Duke loses his mind and challenges Kurt for leadership, but nobody supports him. He takes Myrna prisoner and attempts to escape but once at the group's vehicles he is attacked and killed when he drops a grenade which also kills Myrna. After seeing this Diana retreats and commits suicide by slashing her wrists and her partially eaten body is found by the four remaining survivors. They again retreat and find a recording of a distressed man warning anyone who finds the town that the rats will kill them like they have his friends.
The survivors are once again attacked by the relentless rats and Deus and Kurt sacrifice themselves to barricade the door to allow Video and Chocolate to escape outside where teams in hazmat suits appear from the sewers, gas all the rats and save the pair. As the survivors thank their saviors and remark they are all friends because they are of the same human race, the leader of the rescue team removes his mask, revealing himself to be a humanoid rat.
The herbicide linuron and a mixture of 15 pesticides commonly found in the Italian diet have been assayed for promoting activity in rat liver carcinogenesis. Composition of the pesticide mixture was: benomyl (19.55%); dithiocarbamates (20.67%); thiabendazole (14.94%); diphenylamine (14.25%); chlorthalonil (13.13%); procymidone (7.96%); fenarimol (1.95%); chlorpropham (0.70%); vinchlozolin (0.28%); methidathion (2.37%); chlorpyriphos-ethyl (2.09%); parathionmethyl (1.00%); chlorfenvinphos (0.27%); parathion (0.70%); pyrimiphos-ethyl (0.14%). To determine promoting activity we evaluated induction of preneoplastic foci in diethylnitrosamine-initiated hepatocytes, by positive gammaglutamyl-transpeptidase (GGTase) staining in liver slides, and peroxisome proliferation by peroxisomal-dependent catalase and palmitoyl-CoA-oxidase dosage. For the assay, groups of male Sprague-Dawley rats were initiated with 100 mg/kg diethylnitrosamine intraperitoneally and, one week later, given 150 mg/kg/day linuron or 10 mg/kg/day pesticide mixture, administered by gavage three days a week. All rats were 2/3 hepatectomized at the beginning of the 3rd week. All treatments were terminated at the end of the 8th week, and the rats were sacrificed one week later. No significant increases in number and area (mm2) per slide unit area (cm2) of GGTase-positive foci could be observed in linuron-treated rats (5.84 +/- 1.62/cm2; 0.139 +/- 0.041 mm2/cm2) with respect to controls only initiated with diethylnitrosamine (4.47 +/- 1.30/cm2; 0.182 +/- 0.078 mm2/cm2). After treatment with the pesticide mixture, the number of preneoplastic foci was instead significantly increased (6.91 +/- 2.05/cm2) although the area was not (0.188 +/- 0.128 mm2/cm2). Moreover, no increases in the peroxisome proliferation enzymatic markers were observed in either treated groups. The results imply a possible carcinogenic risk for the population stemming from promoting activities of pesticide mixtures.
About 60 posters went up in the southern canton of Tessin, which borders Italy, criticising the presence of 40,000 Italian workers and "foreign criminals", according to an accompanying website. Underneath the rats is the word 'Balairatt', which means 'rats dance'.
3. What measures and/or instruments has the Commission implemented or does it intend to implement in order to reduce the risk of a possible outbreak of the plague or other diseases that can be transmitted by rats?
Many people are blissfully unaware that they have a rat supermarket in their back garden. If you have a poorly made compost pile, full of half decomposed food, you probably have rats as well. Dogs and cats are a good control, as are anticoagulant poisons, but the best control is to not leave any edible food in your garden. This means having a completely contained compost pile (I use a worm bin partly for this reason).
The city estimates there are about seven million rats in Rome - around 2.5 rats for every resident of the capital - however the Italian Society of Environmental Medicine (SIMA) has estimated that Rome's rat population is about 10 million, which equates to 3.5 rats per every citizen.
APM was not genotoxic in the following tests: dominant lethal mutation assay in rats, host-mediated assay in rats and mice, in vivo cytogenetic assay in rats, and the Ames test (Kotsonis and Hjelle 1996). Results of an assay to measure induction of unscheduled DNA synthesis in rat hepatocytes treated with APM in vitro were negative, indicating the absence of APM-induced DNA damage (Jeffrey and Williams 2000). In a test for the induction of chromosomal aberration in bone marrow cells of male Swiss mice, Mukhopadhyay et al. (2000) reported that a mixture of APM (up to 350 mg/kg) and a second sweetener, acesul-fame potassium (up to 150 mg/kg) administered by gavage was negative. However, a dose-related increase in the percentage of cells with chromosomal aberrations was noted with increasing doses of the two sweeteners, even though the increase was not statistically significant (Mukhopadhyay et al. 2000).
Two long-term feeding carcinogenicity bioassays on APM were performed on rats and one on mice in the early 1970s by the producer Searle & Co. Results were reviewed by the FDA and then summarized in the Federal Register (FDA 1981). To date, the details of the experiments have not been published.
An APM carcinogenicity study was also conducted in Japan during this period (Ishii 1981; Ishii et al. 1981). Groups of 86 male and 86 female Wistar rats were treated with APM in feed at doses of 0, 1, 2, or 4 g/kg bw/day from 6 to 110 weeks of age. No increase in the incidence of brain tumors was observed in the treated groups compared with the controls. Exhaustive experimental details of this study were not published.
Rodents used for the experiment were male and female Sprague-Dawley rats from the colony of the CMCRC/ERF. This colony of rats has been employed for various experiments in the laboratory for nearly 30 years, and extensive historical data are available on the tumor incidence among untreated rats. All control animals were monitored for feed and water consumption and body weight for their life span and, upon death, underwent complete necropsy and histopathologic evaluation.
Once a week for the first 13 weeks, then every 2 weeks until the rats were 110 weeks of age, the mean daily drinking water and feed consumption was measured per cage, and body weight was measured individually. Measurement of body weight continued every 8 weeks until the end of the experiment. The animals were clinically examined for gross changes every 2 weeks for the duration of the experiment. To evaluate the status and behavior of the animals and to limit the postmortem modifications (pmm), a patrol was performed three times daily from Monday through Friday and twice on Saturdays and Sundays and holidays. Dead animals were registered and kept refrigerated at 4C until necropsy. Based on this procedure [part of our longstanding standard operating procedures (SOP)], very few animals were affected by pmm, and only on very rare occasions did this interfere with the ability to histologically diagnose and interpret some lesions.

No evident behavioral changes were observed among treated animals compared with controls. In animals exposed to the highest dose of APM, yellowing of the coat was observed; this change had previously been observed in our laboratory in rats exposed to formaldehyde administered with drinking water (Soffritti et al. 2002b).
