Will Mushrooms Increase Cancer Survival?

Wednesday, September 19th, 2012

A new study published in an open-access article in the journal Evidence-Based Complementary and Alternative medicine concluded that dogs with hemangiosarcoma treated with a compound derived from the Coriolus versicolor mushroom had the longest survival times ever reported for dogs with the disease providing hope that the compound might one day offer cancer patients a viable alternative treatment to chemotherapy. The mushroom commonly known as Yunzhi mushrooms have been used in traditional Chinese medicine for over 2,000 years and is believed to have immune-boosting properties in the compound known as polysaccharopeptine or PSP. Over the past two decades some studies have suggested PSP may also have tumor fighting effects.

To answer the question of whether of not taking PSP increases the life span the researchers studies 15 dogs diagnosed with hemangiosarcoma that were divided into 3 groups of 5. Each group received a different dose of 25, 50, or 100 mg/kg/da of I’m-Yunity, a formulation of PSP that was tested for consistency and good manufacturing processes. Owners were instructed to give their dogs the compound daily and bring them for follow up visits monthly. Blood tests were taken and ultrasound conducted at the visits to determine the extent the tumors developed or grew and spread in the dog’s bodies. Results showed that tumor progression was reduced and life span lengthen. Researchers were shocked and said “Prior to this, the longest reported median survival time of dogs with hemangiosarcoma of the spleen that underwent no further treatment was 86 days. We had dogs that lived beyond a year with nothing other than this mushroom as treatment.”  Although there was no significant differences in the three dose groups longevity the median survival time was highest ion the group receiving 100 mg. at 199 days. Further trials are planned to confirm and extend these findings.

Dogs, Cats, Dust Mites May Increase Allergic Reaction to Hay Fever

A recent study published in the Annals of Allergy. Asthma & Immunology reported that year round allergies to dogs, cats, and dust mites seem to pre-prime the immune system so that symptoms appear earlier or are more severe when confronted by rag weed. In the study researchers wanted to determine why some individuals develop symptoms during ragweed season earlier than others. Testing several perennial allergens they found that being allergic to dogs, cats or dust mites set those suffers up for a quicker onset of hay fever symptoms when exposed to ragweed. In the study 123 people were allergic to ragweed and of these 66% were positive for cat allergies, 63% were allergic to dog allergies and 73% were allergic to dust mites. All were exposed to ragweed for 3 hours and completed symptom questionnaires every 30 minutes during exposure. In general, those who tested positive for dog, cat, and dust mite allergies developed symptoms either faster or to a greater degree than those who tested negative to these. This difference seemed to disappear after 3 hours so that once the hay fever season is in full swing, the differences between the two groups no longer existed. It was suggested that to avoid the overload at the beginning of the hay fever season, sufferers with perennial allergies (dog,cat, dust) should avoid them beforehand or treat their perennial allergy symptoms before hay fever season.
